American Elements specializes in producing high purity uniform shaped Cobalt Oxide Pellets with the highest possible density and smallest possible average grain sizes for use in semiconductor, Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes including Thermal and Electron Beam (E-Beam) Evaporation, Low Temperature Organic Evaporation, Atomic Layer Deposition (ALD), Metallic-Organic and Chemical Vapor Deposition (MOCVD). Our standard Pellet sizes range from 1/8" x 1/8" to 1/4" x 1/4" and 3 mm diameter. We can also provide Pellets outside this range for ultra high puritythin film applications, such as fuel cells and solar energy layers. Materials are produced using crystallization, solid state and other ultra high purification processes such as sublimation. American Elements specializes in producing custom compositions for commercial and research applications and for new proprietary technologies. American Elements also casts any of the rare earth metals and most other advanced materials into rod, bar or plate form, as well as other machined shapes and through other processes such as nanoparticles (See also application discussion at Nanotechnology Information and at Quantum Dots) and in the form of solutions and organometallics. We also produce Cobalt Oxide as pieces, tablets, powder, and sputtering target. Oxide compounds are not conductive to electricity. However, certain perovskite structured oxides are electronically conductive finding application in the cathode of solid oxide fuel cells and oxygen generation systems. See research below. Other shapes are available by request.
Cobalt is a Block D, Group 9, Period 4 element. The number of electrons in each of Cobalt's shells is 2, 8, 15, 2 and its electronic configuration is [Ar] 3d7 4s2. In its elemental form cobalt's CAS number is 7440-48-4. The cobalt atom has a radius of 125.3.pm and it's Van der Waals radius is 200.pm. Cobalt and its compounds are somewhat toxic by skin contact and moderately toxic by inhalation. Cobalt has a metallic permeability two thirds that of iron. It exists as a mixture of two allotropes over a wide temperature range. The transformation is slow and accounts in part for the wide variation in the physical properties of cobalt. It is alloyed with iron, nickel and other metals to make Alnico, an alloy of unusual magnetic strength with many important uses. Samarium-cobalt is one of the highest strength magnet alloys known. Cobalt compounds produce a brilliant and permanent blue color in ceramic glazes, glass, pottery, tiles, and enamels. Co-60 is useful as a gamma ray source. Toxicity of cobalt and its compounds are mild by skin contact and moderate by ingestion. Cobalt 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. Cobalt was first discovered by George Brandt in 1737. The origin of the word Cobalt comes from the German word 'Kobalt or Kobold' which translates as "goblin", "elf" or "evil spirit". See Cobalt research below.
