Columbia produces the most emerald in the world, where the Muzo mine and eastern emerald belt are located. Beryllium is made by reducing beryllium fluoride with magnesium metal in the following equation:Įmerald is less common than diamond and more expensive than gold. In the U.S., beryllium is mainly mined at Gold Hill and Spor Mountain in Utah, and in Alaska on the Seward Peninsula.īeryllium metal began commercial production in 1957, but did not live up to its expectation of expanding the industry. Bertrandite (Be 4Si 2O 7(OH) 2) contains less than 1% Be and is the main beryllium mineral mined in the U.S., while beryl (Be 3Al 2(SiO 3) 6 is mined in other countries and contains approximately 4% Be. Of the many beryllium minerals, only two are of commercial importance in the preparation of beryllium metal and its compounds. Beryllium is also present in precious gems such as aquamarine, bixbite, and emerald. BeO is a white solid that has a high melting point, making it useful in engines, radio equipment, and semiconductor devices.īeryllium is in approximately 100 of the 4000 known minerals, such as bertrandite, beryl, chrysoberyl, and phenakite. Beryllium dissolves easily in non-oxidizing acids, such as HCl, with the exception of nitric because it forms the oxide making it very similar to aluminum metal.īeryllium combines with many non-metals to form binary compounds, such as beryllium oxide (BeO). However, when it is ignited, beryllium burns brightly making beryllium oxide and beryllium nitride. Beryllium forms an oxide layer making it not react with air or water even in extreme heat. With a small atomic radius, Be 2 + has high polarization characteristics allowing it to form many covalent bonds.
Like all elements in the 2nd group on the periodic table, beryllium has +2 oxidation state.

Due to its light, stiff, and stable structure, beryllium alloys are being used in industrial work more and more. Download 400 Beryllium Atom Stock Illustrations, Vectors & Clipart for FREE or amazingly low. Common compounds containing beryllium are emerald and aquamarine. This thin layer of oxide allows beryllium to scratch glass. In its purest form, beryllium is a steel-gray and lightweight alkaline earth metal.īeryllium is a steel-gray metal that tarnishes slowly in the air due to oxide forming around it. With magnesium and aluminum, beryllium forms the oxide mineral taafeite.Ĭompounds of beryllium are very poisonous - dust or powder from the metal or its oxides can cause serious illness.\( \newcommand\)īeryllium is an element found in nature and is combined with other elements in minerals, including beryl and chrysoberyl.
With boron, beryllium forms the oxide mineral Hambergite. With aluminum, beryllium forms the oxide mineral Chrysoberyl including a gem-quality variety called Alexandrite. A silicate of beryllium with sodium is epididymite. A silicate of beryllium with sodium and aluminum is tugtupite. Another silicate mineral of beryllium is euclase. It is found with yttrium in the silicate mineral gadolinite. Other silicates of beryllium are leucophanite, helvite and milarite. Beryllium is also found in the silicate mineral Bertrandite. Beryllium is found in the phosphate minerals Beryllonite, Herderite and roscherite.īeryllium forms the silicate phenakite, Be 2SiO 4. Aquamarine is also a bluegreen variety of beryl. Also of gem quality is trapiche, or trapiche emerald, which is a green gem with a marked spoke pattern. Gem varieties of beryl include emerald, which is beryl with traces of chromium to contribute the green color. The principal ore of beryllium is beryl, Be 3Al 2(SiO 3) 6. About 2% of beryllium in copper produces a hard alloy used for making springs. X-rays readily penetrate materials of low atomic number, and beryllium metal has the best mechanical properties for the production of such windows.īeryllium is also used in specialty alloys.

It is used for making windows for x-ray tubes and radiation counters. Beryllium is a light, silvery-white metal.
