Beryllium information, including Technical Data, Safety Data and its high purity properties, research, applications and other useful facts are discussed below. Scientific facts such as the atomic structure, ionization energy, abundance on Earth, conductivity and thermal properties are included.
Beryllium is most commonly used in alloys with our base metallic materials. As a 1 - 3% addition to copper it produces "beryllium bronze", a highly wear resistant material and with nickel it is used to make spot welder electrodes. Beryllium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. It is used as a coating on X-ray tubes because it is transparent to the X-ray range. It emits neutrons on bombardment by alpha rays. It also has applications in the nuclear industry. Beryllium facts, including appearance, CAS #, and molecular formula and safety data, research and properties are
Oxides are available in forms including powders and dense pellets for such uses as optical coating and thin film applications. Oxides tend to be insoluble. Fluorides are another insoluble form for uses in which oxygen is undesirable such as metallurgy, chemical and physical vapor deposition and in some optical coatings. Beryllium is available in soluble forms including chlorides, nitrates and acetates. These compounds are also manufactured as solutions at specified stoichiometries. Beryllium is a Block S, Group 2, Period 2 element. The electronic configuration is [He] 2s2. In its elemental form beryllium's CAS number is 7440-41-7. The beryllium atom has a radius of 111.3.pm and it's Van der Waals radius is 200.pm.All elemental metals, compounds and solutions may be synthesized in ultra high purity (e.g. 99.999%) for laboratory standards, advanced electronic, metallurgy and optical materials and other high technology advantages. Information is provided for stable (non-radioactive) isotopes. Organo-Metallic Beryllium compounds are soluble in organic or non-aqueous solvents. See Analytical Services for information on available certified chemical and physical analysis techniques including MS-ICP, X-Ray Diffraction, PSD and Surface Area (BET) analysis. Beryllium was first discovered by Abbé René-Just Hauy in 1798.
