By the 1950s, the metal had become vital for a variety of high-tech applications. Historically, beryllium's sole source was beryl [beryllium aluminum silicate, Be3Al2Si6O18], which was obtained only from a small number of granite pegmatites. But most of these were already mined out, and the United States was forced to import beryl.

Elements in focus: beryllium. As a lightweight, super-strong metal, beryllium is an engineer's dream – but it also has some less convenient qualities. The element beryllium is perhaps one of the strangest in the periodic table. It is the second lightest metal (by atomic mass), after lithium, and it is also surprisingly unreactive …

Beryllium is a chemical element with the symbol Be Beryllium has the atomic number 4. Named after beryl, a semiprecious mineral, from which it was first isolated It is a steel-gray, strong, lightweight and brittle alkaline earth metal. Notable gemstones high in beryllium include beryl and chrysoberyl.

A bivalent element, beryllium is a steel grey metal that can be mostly found in the minerals, the most important of which are beryl (Be 3 Al 2 Si 6 O 18), also called emerald and aquamarine according to its color, and chrysoberyl (A l2 BeO 4). Pure beryllium is obtained by reduction of beryl or by electrolysis of beryllium chloride.

Beryllium is a Gray Solid Beryllium naturally occurs in the earth's rocks. There are approximately 45 mineralized forms of beryllium. The two that are most frequently mined are beryl and bertrandite. Beryl is also well known as the gemstones emerald, aquamarine, and beryl. Beryllium exists as a solid and is part of the metal family.

Of the many beryllium minerals, only two are of commercial importance in the preparation of beryllium metal and its compounds. Bertrandite (Be 4 Si 2 O 7 (OH) 2 ) contains less than 1% Be and is the main beryllium mineral mined in the U.S., while beryl (Be 3 Al 2 (SiO 3 ) 6 is mined in other countries and contains approximately 4% Be.

Beryllium metal is extracted from beryl and bertrandite. While beryl is found in granite and pegmatite dikes, bertrandite is found in large low-grade deposits. Classified as an extremely coarse-grained rock, pegmatites are renowned for the material they contain, including rare-earth elements, gems, bismuth, lithium and beryl. ...

Key Points. Anyone working with or around beryllium metal, ceramics, alloys, or salts is at risk of developing beryllium sensitization or disease from inhaling small particles. Very low concentrations of beryllium in air can cause sensitization and disease. People living near a plant that uses beryllium and families of workers have developed ...

Beryllium Geology. Beryl, a silicate of aluminum and beryllium, is found along with other beryllium minerals in pegmatite dikes. Large quantities have been taken out of some feldspar mines. The metal beryllium is much like aluminum, but is about a third lighter, and is as hard as steel. It is also about four times as elastic as aluminum, and 25 ...

Sources. Beryllium is found in some 30 mineral species, the most important of which are bertrandite, beryl, chrysoberyl, and phenacite. Aquamarine and emerald are precious forms of beryl. Beryl and bertrandite are the most important commercial sources of the element and its compounds. Most of the metal is now prepared by reducing beryllium ...

The three most common beryllium-bearing minerals found in economic deposits are beryl (Be 3 Al 2 Si 6 O 18), bertrandite (Be 4 Si 2 O 7 (OH) 2, and phenakite (Be 2 SiO 4).

Beryllium is a lightweight, strong, steel-gray metal. It is also quite brittle, meaning it breaks easily under stress but tends not to deform until the moment it fractures (similar to glass or ceramic). Beryllium occurs …

Isolation of Beryllium. Beryllium metal is most commonly extracted from two ores: beryl and bertrandite. Beryl ore contains roughly 2-4% beryllium, while bertrandite ore typically contains less than 0.5% beryllium. The refining processes of beryl and bertrandite are quite similar and can be carried out together.

Beryllium is found in about 30 different mineral species. The most important are beryl (beryllium aluminium silicate) and bertrandite (beryllium silicate). Emerald and …

Pure beryllium, one of the lightest metals known, is a hard, grayish material obtained from the minerals bertrandite and beryl. Gem-quality beryl is known as either aquamarine or emerald.
