Beryllium Carbide is
available in numerous forms and custom shapes including Ingot, foil, rod, plate and sputtering target. High purity forms also include Carbide powder, submicron powder and nanoscale, single crystal or polycrystalline forms. Arsenic Carbide is generally immediately available in most volumes.American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia)and follows applicable ASTM testing standards.Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.
Like diamond, a pure carbon compound, Carbide compounds tend to be extremely hard, refractory and resistant to wear, corrosion and heat, making them excellent candidates for coatings for drills and other tools. They often have other valuable properties in combination with toughness, such as electrical conductivity, low thermal expansion and abrasiveness.
Beryllium is a Block S, Group 2, Period 2 element. The number of electrons in each of Beryllium's shells is 2, 2 and its 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. Beryllium and its salts are toxic as well as carcinogenic. 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 was first discovered by Abbé René-Just Hauy in 1798. The origin of the name Beryllium comes from the Greek word 'beryllos' meaning beryl. See Beryllium research below.
