"Lighter than aluminum, harder than steel"
Copyrighted© 2002 by Lindsey V. Maness, Jr.
Beryllium is best known as a component of its namesake mineral, beryl, whose most precious gem variety is Emerald. Beryllium's unique physical and chemical characteristics are propelling it into the forefront of 21st Century indispensable industrial feed-stock chemicals.
Beryllium is, indeed, "Lighter than aluminum, harder than steel," a slogan used by the aerospace industry in the 1950s. The slogan, while catchy, does not tell the entire story of this element whose great promise is limited by great dangers to those reckless of its risks.
As an alloying metal, Be has very useful characteristics. Less than 2% Be in Cu makes an alloy harder than some steels. Differing alloys yield wildly different features, from electrically very conductive to non-conductive and with heat transfer (generally excellent) almost specificable.
References used in this compilation are at the end of this document. Since there is some variation in sources (e.g., prices & terms) and details summarized, readers are strongly encouraged to consult the original references cited.
Beryllium (Be) was named for its chief mineral, beryl (from the Greek: beryllos). Chemist Louis Nicolas Vauquelin discovered beryllium in its oxide, beryllia, in 1797. Friedrick Wöhler and Alexandre Brutus Bussy both independently isolated the element in 1828. Since the soluble salts of Be have a sweet taste, Be was first named glucinium (or glucinum), after glucose, a common sugar. The taste is still a diagnostic means of identification of Be salts, but is not recommended because of the danger of the procedure to the tester. Non-toxic Be minerals include bertrandite, beryl, chrysoberyl (aka alexandrite, but only if with color change) and phenakite (aka phenacite).
Physical & Chemical Characteristics:
Be is atomic number 4, in group IIa (alkaline earths) of the periodic table of elements. The periodic table column is: Be, Mg, Ca, Sr, Ba and Ra. Electron Configuration is [He]2s2.
- Atomic Weight = 9.012182
- Always Be+2 cation in compounds
- Clarke Number (Relative Abundance) = 0.0006% by weight of earth's crust
- Color = Silverywhite, lustrous
- Be salts hydrolyze into acid solutions (amphoteric)
- BeO is amphoteric (has both acid & base properties)
- Be(OH)2 is amphoteric

- Boiling Point = ~2,970oC ~5432 oF (Very high)
- Unaffected by air or H2O, even at red heat.
- Specific Gravity = ~1.848 g/cc (almost twice as heavy as water)
- Hardness = variable (alloys are usually harder than steel). Ultrapure Be is relatively soft.
- Nonsparking (especially in Cu alloys)
- Conducts electricity
- Very brittle in pure metallic form
- Tarnishes to oxide, enabling it to cut glass

- Very similar to corresponding aluminum (Al) compounds
- Equally electronegative as Al, forming covalent bonds
- Forms protective oxide coating, like Al
- Difficult to separate Be from Al
- Most Beminerals are silicates or phosphates: some of the remaining are borates or sulfides.
- No simple tests exist to determine Be.
- Be is usually detected via Atomic Absorption and Atomic Emission spectroscopy.
Isotope (Natural) = 9Be. Atomic mass = 9.0121822. Stable. 100.0000% in nature.
Isotopes (Radionuclides) total less than 10-6 of Be in nature:

7Be, 8Be and 10Be are produced by cosmic rays in the upper atmosphere, or artifically made in nuclear reactors.
To Beneficate Be:
- Sinter ores with CaF2: leach BeF2 (very toxic) with H2O.
- Fuse ores and leach BeSO4 with H2SO4.
Note: Be is extracted from Utah's Bertrandite ore concentrate by leaching with H2SO4 at a plant near Delta, UT. After further processing, the end product is Be(OH)2, which is shipped to Brush Wellman's plant in Elmore, OH, where it is converted into beryllium oxide, alloys and metal.
To Make Be Metal:
- Heat BeF2 with Mg.
- Electrolyze BeCl2 with NaCl.
Alloys (especially with Cu):
- Hardener (2% Be with Cu is harder than some steels)
- Improve casting qualities
- Better insulating properties
- Usually have high heat resistance
- Usually have higher melting point
- Can be an excellent conductor of heat
- Improves corrosion resistance

- Ceramics (e.g., at Coors Ceramics). Beenriched ceramics can be designed to have a thermal expansion coefficient of less than 1.0; however, it is more common to manufacture them with a null thermal expansion coefficient. In the first case, ceramics will actually shrink upon heating; in the second case, ceramics will retain their original size without regard to ordinarilyencountered temperatures. Most substances increase in size upon heating. Montmorillonitebased Beclay ceramics can be designed to have especially desirable or unusual characteristics. It is quite likely that highperformance automobile engines will be manufactured routinely in the near future from such ceramics: advantages will include significantly improved mileage, drastically lowered weight and ability to operate at much higher temperatures.

Exploration for Beryllium
The Integrated Exploration Approach is clearly superior to any single technique used alone, especially when taking advantage of modern Geographic Information Systems (GIS) technology. In the Integrated Exploration Approach, geologists determine and evaluate (starting with a Literature Search for relevant publications and maps) the most likely areas for Be enrichment and delineate specific areas for further data gathering. Such data gathering includes: Geochemical Prospecting, Field Geology (including testing "Prospect Pits" and, perhaps, core drilling, etc.), Geophysical Prospecting and Status of Land Ownership. As the data are gathered, the team of specialists, working together, determine on an ongoing basis where to further focus efforts. When especially promising sites are reasonably firmly confirmed, legal rights to mine the prospects are acquired. As mining commences, the geologist continues to integrate new information as gathered, in cooperation with geophysicists (i.e., Berylometer datagathering and analysis) and mining engineers, in support of management's goals.

- Field Geology, including sampling, geological mapping (ages & types of rocks and stage of metamorphism; faults, fractures and folds, mineralization zones, etc.), identification of minerals & rocks, etc.,
- Drilling & Coring
- Geophysical Exploration
- Berylometer. The Berylometer enables the direct detection and estimation of quantity of beryllium for any place closely (~1 cm distance) accessible to the instrument. For data acquisition, the Berylometer is usually mounted on a sledlike wagon and pulled or driven over the ground along wellsurveyed lines, usually in a grid pattern. Since the Berylometer carries a very "hot" radioactive emitter (124Sb), it must be thicklyencased in lead for safe operation: this makes the sled heavy, awkward and hazardous (in several respects); further, special licenses for handling radioactive materials must be acquired from the US Department of Energy and its radioactive "energy source shield" must be replaced every two months due to the rapid radioactive decay of 124Sb. The Berylometer makes possible prospecting for any and all Becontaining minerals, even in very low concentrations: this device provides unique exploration capabilities for Be and is thereby worthy of separate special mention. The Berylometer is manufactured by John Birmingham, CEO & Owner of Boulder Scientific Company, P.O. Box 548 (598 Third Street), Mead, CO 805420548 USA, Tel: 9705354494 or 3034421199, Fax: 9705354584, Web-Site: http://www.boudersci.com/welcome.htm. Originally, all Berylometers were manufactured by the Boulder Scientific Company, but that may have changed. The largest single user of Berylometers in the USA is almost certainly BrushWellman and its contractors for its operations in Utah.
- 124Sb is gamma radiation (hard radiation) source.
- 9Be, when subjected to (1.67 MeV: near Be's neutronbinding energy) gamma radiation, releases a neutron fast.
- The 9Be decays into 8Be, with a halflife of ~7x10-17s, which then decays into two 4He (alpha particles), with 17.2MeV of energy released and 0.01862 atomic mass units lost. This part is not relevant to the Berylometer, which ignores all the "daughter products" of the radioactive decay.
- The Original Berylometer Works as Follows:
- The neutrons released, after passage through a "neutron moderator" (polyethylene or other plastic [which also stops alpha particles]), are captured by Boron Tetrafluoride, which releases alpha particles, which are detected by an instrument similar in principle to standard GeigerMueller type instruments (i.e., Geiger Detectors).
- Using recordings of the "Geiger Counter" readings, maps are drawn displaying Be concentration in partsperthousand (PPT) and contoured to enable planning the mostefficient mining at lowest cost.
- The Modern Berylometer Works as Follows:
- The neutrons released, after passage through a "neutron moderator" (polyethylene or other plastic), are counted directly by a far more accurate and far more efficient 3He tube (neutron flux). The data are automatically recorded as gathered.
- The neutron flux data are used to render maps displaying Be concentration in partsperthousand (PPT) and contoured to enable planning the mostefficient mining at lowest cost. Flags are placed around areas of special enrichment as data are gathered to further optimize mining operations.

Some of Maness' Speculations about Beryllium:
Be (ionic radius 0.31 nm) is very similar to Si (0.41 nm) enabling Be to displace Si. Be is widely disseminated in trace amounts in Si-bearing rocks, which tend to disperse it widely in the earth's rocks, with the consequence that Be is not usually concentrated. Since Be has such profound effects in alloys and is of similar ionic size, might it also have effects out of all proportion in Si used for computer chips? Might the Si chips benefit from either the addition of (dopant) Be or the removal of all Be?
Geobotany. Be has a very significant effect on plant life. The production of higher plants (monocotyledons & dicotyledons) is inhibited by ~50% by only 16 ppm Be! In contrast, certain lower plants (e.g., some algae) can benefit from the presence of Be. The logical question concerns possible geobotanical applications. Using properly-enhanced satellite imagery (Maness' special expertise) to infer degrees of mineralization within a formation should be possible, as should using the same imagery to search for previously unknown Be-mineralized areas. It would also be reasonable to suspect (although presently not adequately researched) that, with such a strong effect on higher plants, Be would be incorporated into (and concentrated in) plant tissues. It has been shown, for example, that Be in Be-mineralized areas is concentrated in the wood of (but not the leaves of) Ash trees. Testing the appropriate plant ashes for Be should be a useful exploration and delineation tool for a variety of geological mineral suites.
Be tends to bind very tightly to montmorillonite but not to kaolinite. Once adsorbed, it will not be displaced even by high concentrations of Mg, Ca or Ba. How does Be act in illite and other clays? Might this peculiarity be turned to practical use? Does the affinity of Be with certain clays explain, at least in part, the high concentration of Be in some ultramafic schistose (phlogopitic) rocks? Might some clays be mineable for Be? (A large proportion of the Be acquired at Spor Mountain, UT, is from Montmorillonitic clays.) Might some bauxite ores (which are clayrich) have economicallyrecoverable Be as a byproduct of Al production? Could some clays be used to trap Be pollutants (e.g., in flue gases)? Might some clays be usable to beneficate Be ores?
Be is present in some coals and in some oils. Might Be be recovered from coal ash or flue stacks or oil refineries? Should special care be utilized to determine amounts of Be in coal before burning to minimize health risks? In oil refineries, might Be be a catalyst (positive or negative)?
10Be/9Be ratio has been used to calculate rates of sedimentation of fine materials, and may have other, similar uses (e.g., age dating).
In at least one case, a Pb-Zn-Ag smelter (in Kosovo) is claimed to have been expelling a significant quantity of Be in flue-gases, leading Maness to wonder if perhaps unrecognized disseminated(?) Be deposits are associated with some types of massive sulfides. Some of the Be minerals listed herein (e.g., Danalite, Genthelvite & Helvite) are sulfides. Sphalerite (SE USA) and pyrite (various places) have been noted, pre-smelting, with elevated levels of Be, but no records of flue-particulate analyses of Be are known. The cost of modernizing the Kosovo smelter to recover fine particulates might be recovered from selling the Be, and other, flue concentrates. This would clearly be of immense benefit to the impoverished local economy. Of equal importance, the health benefits to the nearby populace of modernizing the smelter to remove Be are obvious. Numerous reports of respiratory distress near the smelter have been made, but none are known to have explicitly stated any confirmed cases of berylliosis. It is unlikely that berylliosis was even considered as a diagnosis: it would be irresponsible not to check. In actual fact, there are just as many reports stating that the air in the proximity of the smelter is within acceptable health limits as claim the opposite: KFOR (Allied Military Forces in Kosovo) have somewhat disingenuously firmly endorsed both opposing sides of this issue to conform with changing political exigencies. The presence of Be associated with the smelter has been presented by environmental groups as proof of the presence of a secret nuclear reactor in the area: such hysterical accusations are, unfortunately, not any surprise considering the biased and uninformed nature of the sources and their extreme (Greens Party) political agendas. A simple comparative test of isotopes of Be present would quickly resolve these allegations about a possible nuclear reactor in the area. And, finally, there is reasonable doubt about whether Be is even being emitted at the alleged levels: the studies quoted (by the Greens) may have been seriously flawed. Truth is what is important.
In Maness' OPINION (and that of several other experts), the reasons for the toxicity of beryllium metal particulates include the greatly increased surface area (by several orders of magnitude) of finely-ground particles vs. solid metal; the great increase in "edge effect," whereby single-molecule thickness along particle edges experience great differences in chemical reactivity (in effect, a catalyst); and the fact that beryllium is, itself, amphoteric, enabling its oxide and hydroxide coatings to be readily either an electron donor or an electron recipient (i.e., properties of either an acid or a base), greatly magnifying its chemical reactivity. These unique characteristics of Be can reasonably be predicted to eventually lead to some highly-beneficial medical advances. Certainly, vigorous medical research should proceed, both to further understand the scourge of berylliosis and the possibly salubrious advantages that Be might offer to medical science. At this point, however, these views and hypotheses are only opinion.
Hazards of Beryllium:
Berylliosis, to the genetically susceptible (~510% of the population: approximately 1/2 of whom are asymptomatic and whose reaction to Be can be determined only by use of recentlydeveloped medical tests), is a very severe (usually fatal) respiratory illness caused by the inhalation of extremely toxic beryllium metal particulates or metal oxides or fumes. Berylliosis is treatable, but not curable. The consensus of opinion appears to be that berylliosis is caused by soluble compounds of Be (regardless of means of introduction into the body), and that the more soluble the compound, the greater the toxicity. The latency period can vary, with the first symptoms often appearing years after exposure. While the solid metallic form of Be is considered non-hazardous, probably because it does not solubilize readily into toxic compounds, the safe milling or machining of the metal requires the stringent implementation of precautions preventing exposure to Be dust particles (even within a metal alloy), which are extremely toxic. The exposure of people to Be dust at Rocky Flats Nuclear Weapons Center led to numerous cases of berylliosis in Colorado: in response, National Jewish Hospital (now National Jewish Medical and Research Center, 1400 Jackson Street, Denver, CO 802062761, Tel: 3033884461 or 800222LUNG) developed what many consider to be the world's foremost treatment and research facility for berylliosis. To do so, National Jewish built upon its existing first-class competence in treating tuberculosis. U.S. News & World Report ranked National Jewish "the #1 Respiratory Hospital in America four years in a row" (1998-2001). Those who experience several of the following symptoms and have had exposure to Be dust or fumes should seek specialized medical attention to determine whether or not berylliosis is the cause.
Symptoms of Berylliosis (Beryllium Poisoning)
aka Chronic Beryllium Disease (CBD)
- Persistent Coughing
- Shortness of Breath with Physical Exertion
- Chest and Joint Pain
- Blood in the Sputum
- Rapid Heart Rate
- Loss of Appetite
- Fevers and Night Sweats
Be is considered to be a borderline carcinogen by some health agencies; however, the effects vary widely by Be compound, conditions of exposure and among the exposed population.
Further, while systemic absorption of Be through the skin is limited, ionic Be can react with tissue causing an immune response. Be materials embedded in skin can prevent the healing of wounds. Only a few percent of exposed populations are susceptible to Be diseases. Different Be compounds differ greatly in toxicity (from none to acute) and there is no apparent relation between the severity of Be diseases and the extent of exposure. Synergistic effects with other dust-borne irritants introduce complications. Less than a day of exposure to Be dust has not been shown to initiate symptoms of an acute Be intoxication.
Beryllium Minerals (NOT Comprehensive):
Approximate weight % of Be follows each formula: the more atomic substitution possible, the more variation in weight percent to be expected. For some of the more complexly varied minerals (those whose atomic weights were not listed in references cited), the atomic weights for the "endmembers" were calculated using solely the most common elements (or Be, when a listed substitute, e.g., Semenovite). Such calculated molecular weights and percentages are in [brackets]. For example, the weight percent of Be for Asbecasite was calculated using the endmember formula: Ca3TiBe2As3O6(SiO4)2.

Gem Varieties of Beryl:
Aquamarine light to dark blue or blue-green. The largest (~110.3 kg, or ~243 lbs.) known aquamarine crystal in the world was mined in 1910 in the Marambaia, in Minas Gerais State, Brazil. Several blue or blue-green gem stones can be confused with (or misrepresented as) aquamarines, including euclase, spinel, topaz, tourmaline and zircon. Some of the fraudulent names for aquamarine include "Brazilian Aquamarine" (blue topaz), "Mass Aqua" (blue glass), "Nerchinsk Aquamarine" (blue topaz), "Siam Aquamarine" (heat-treated blue zircon) and "Synthetic Aquamarine" (synthetic blue spinel).
Bixbite strawberry red. Same as "Red Beryl." Bixbite is easily confused with strawberry red topaz and spinel. The AGI no longer acknowledges "Bixbite" as a valid gem stone name, in part because another (non-Be) mineral, "Bixbyite," was named for the same person and some consider it unfair to have two minerals named after the same person. Sour grapes? The name Bixbite remains in wide, although declining, use.
Blue Beryl Blue. Blue Beryl can be confused with sapphire and tanzanite.
Emerald green to dark green. Emeralds are considered the most valuable type of beryl, with the Trapiche Emerald (star-shaped rays from the center) the most valuable form. Synthetic emeralds are of far lower value and are often identified by the names: "Biron Emerald," "Chatham Emerald," "Gilson Emerald," "Kimberly Emerald," "Lennix Emerald," "Linde Emerald," "Regency Emerald," and "Zerfass Emerald." Fraudulent "emeralds" abound, with colored glass being the most common, including "Broghton Emerald," "Endura Emerald," "Ferrer's Emerald," "Medina Emerald," "Mount St. Helens Emerald," and "Spanish Emerald." Emerald doublets are created by gluing together two pale green stones (or glass) with green glue. Other Fraudulent "emeralds" include "African Emerald" (green fluorite), "Bohemian Emerald" (green fluorite), "Cape Emerald" (prehnite), "Congo Emerald" (dioptase), "Emeraldine" (green-dyed chalcedony), "Emeraldite" (green tourmaline), "Evening Emerald" (peridot), "Indian Emerald" (green-dyed quartz or chalcedony), "Lithia Emerald" (hiddenite), "Mascot Emerald" (emerald doublet), "Night Emerald" (peridot), "Oriental Emerald" (green sapphire), "South African Emerald" (green fluorite), "Tecla Emerald" (emerald doublet), "Transvaal Emerald" (green fluorite), and "Uralian Emerald" (demantoid garnet). In general, several green gem stones resemble emeralds and may be confused with, or misrepresented as emeralds, including: diopside, dioptase, garnet, hiddenite, peridot, tourmaline and zircon.
Golden Beryl golden yellow. Golden beryl can be confused with chrysoberyl and topaz.
Goshenite colorless to white. Goshenite is easily confused with other colorless gem stones, in particular with diamond, rock crystal, sapphire and spinel.
Green Beryl pale green or grass green. Green beryl is easily confused with grass green hiddenite, garnet and zircon.
Heliodor yellow, yellow-green or brown. Heliodor is easily confused with many gem stones, in particular with chrysoberyl, citrine, topaz and zircon.
Morganite pink to light purple. Morganite can be confused with rose quartz.
Peach Beryl orange-pink. Peach beryl is very similar to the padparadschah form of sapphire, and to orange-pink forms of spinel and topaz.
Red Beryl deep red. aka Bixbite, etc. Red beryl is very distinctive, being a deeper red than even ruby and ruby spinel. True Red Beryl is found in only one place, the Wah Wah Mountains of Beaver Co., Utah, where it occurs in fractures in a rhyolite around the rim of an extinct volcanic caldera. Numerous names for this extremely rare and highly-desirable gem-quality beryl have been proposed. The new mine owners may choose an unique name that will more adequately describe the beauty of this truly emperor of gems.
Notes about beryl:
1. The original cut emerald gemstones of the Old Testament Era owed their green color to Fe, not to Cr. Those which have been recovered from Middle Eastern archeological sites (e.g., those in the British Museum) were all uniquely characteristic of a now-depleted ancient emerald mine near the Western shore of the Red Sea in Egypt. Its geological equivalent on the Eastern shore of the Red Sea in Saudi Arabia has been being mined for "emeralds" since the mid-1980s for the Saudi Royal Family by the French firm, BRGM. It is the very essence of irony that, according to the recently-changed definitions of the AGI, the original biblical "emeralds" would no longer qualify as such, but would be disparagingly dismissed as "green beryls."
2. Beryls are not always perfect hexagonal well-terminated prisms, but can also infrequently occur as short, stubby crystals, tabular crystals, plates, columnar aggregates or in massive form. Beryls are only rarely found in druzy or platy aggregates or as bundles of thin, elongated crystals. Beryl crystals are usually very-finely striated lengthwise, although it is not uncommon to find them with a silky-sheen surface (e.g., North Carolina and Russia).
3. Pure beryl is colorless. Impurities cause the colors of the various gemstones, with Cr (or V) making green emeralds and Fe making blue-green aquamarines.
4. Beryls occasionally fluoresce in yellow, light blue, purple, pink or red.
5. Fine gem-quality emeralds have been mined at Muzo and Chivor in Colombia; from Minas Gerais in Brazil; from the Ural Mountains in Russia; from the Cobra and Somerset Mines in Transvaal, South Africa; from the Habatchal in Austria; from Sagadahoc County and Oxford County, Maine; from Branchville and Haddam Neck, Connecticut; from Grafton County, New Hampshire; and from numerous mines in Alexander County and Cleveland County in North Carolina. There are also many undocumented emerald mines in South Carolina whose production is sold at periodic unadvertised auctions near Spruce Pine, NC. It is Maness' strong professional opinion that a belt of Emerald-prone rocks (beryl-containing pegmatites intruded through Cr-rich rocks) extends along the Eastern flank of the Appalachian Mountains from South Carolina, through North Carolina, Virginia, Maryland, etc., into Eastern Canada.
6. Colorado has several proven beryllium deposits (Mount Antero, Badger Flats, etc.) which have yielded magnificent specimens of aquamarine, "green beryl," goshenite, etc. Indeed, for this reason, aquamarine is the Colorado State Stone. Several now-closed mines west of Boulder, CO, yielded huge (up to two feet in diameter!) beryl crystals that were stony, but with significant (recoverable for cutting into gem stones) streaks of gem-quality deep-green or blue-green material. The "gem-quality streaks" alway cut ~90o across the longest dimension (length) of the beryl crystals.
7. Beryls have an alkaline affinity and are commonly mined from (quartz-rich) alaskite or pegmatitic rocks. Beryls historically comprise the largest single source of ore for the production of Be metal, although Utah's bertrandite may have overtaken beryl in yearly worldwide tonnage mined (as it has in the USA). Behoite ore was, for some time, a significant source; however, with the closure (allegedly due to safety-costs and -concerns) of the Texas mine, Behoite is no longer known as an ore source from any locality. Behoite's toxicity is such that miners had to wear "moon suits" at work. Beryls (and bertrandite) are usually found in association with quartz, feldspar, muscovite, cassiterite, spodumene, calcite, pyrite, tourmaline, apatite, barite and dolomite. Some tin, tungsten and spodumene mines have produced substantial quantities of beryls.
8. The conventionally accepted views regarding the geology of the emeralds of Brazil and Colombia are problematic: there are just too many things that do not fit comfortably, and that persist over too large a region to be unique, localized, events. Are the host rocks really schists, or only schistose? Are they really metasomatized sediments of ultramafic composition or might they actually be (as seems likely in some cases!) metasomatized ultramafic intrusives? The distinction is far more than only a useless academic exercise: true understanding of the geology could lead both to new discoveries and to extensions of mines. Equally critical is a more complete knowledge of the structure of these deposits. Is the mineralization fault (gouge) related? Are the deposits along the plane of intraformational (thrust) faults? What were the chemical processes of concentration of Be? What component of the mineralization is due to migrating fluids? Was the Cr and/or Be present from the beginning (remobilized into emeralds) or introduced later? Many of these questions can be answered, or at least limited in scope, by a more precise (absolute, not just relative: younger or older) determination of the time relationships of minerals and geological units.
9. Beryls are frequently treated to increase their value. Green beryls (Fe) are often heated to 450oC (842oF) to form a deep-blue aquamarine. Fractured emeralds are usually treated with an oil to mask imperfections. Irradiation can also remove minute flaws. While such activities are not prima-facie fraudulent, it is desirable for those in the business (and for informed consumers!) to be aware of such processes and their implications (ethical, professional & legal).
10. The chemical formula for beryl given on the Encarta® web-site is wrong.
