See research below. American Elements specializes in producing Cobalt as plates in various thicknesses and sizes. Most plates are cast for use in coating and thin film 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), Organometallic and Chemical Vapor Deposition (MOCVD) for specific applications such as fuel cells and solar energy. Thicknesses start at 0.25" for all metals. 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 as rods, powder and plates. 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 its 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. In certain circumstances, cobalt has the ability to mimic the reactivity of precious metals (such as platinum and palladium), as researchers from the Los Alamos National Laboratory discovered in a November 2012 experiment, and may prove useful as an inexpensive industrial catalyst for green energy applications such as biofuels and the reduction of carbon dioxide. 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 is found in cobaltite, erythrite, glaucodot and skutterudite ores. 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.
