American Elements: Cobalt Oxide Rotatable Sputtering Target Supplier & Tech Info

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 Pharmacopeia/British Pharmacopeia) and follows applicable ASTM testing standards.See safety data and research below and pricing/lead time above. American Elements specializes in producing high purity Cobalt Oxide Rotatable Sputtering Targets with the highest possible density and smallest possible average grain sizes for use in semiconductor, photovoltaic, and coating applications by chemical vapor deposition (CVD) and physical vapor deposition (PVD) and optical applications. 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. Our standard Rotatable Targets for large area thin film deposition are produced either by spray coating on a tubular substrate or casting of a solid tube. Rotary Targets are available with dimensions and configurations up to 1,000 mm in length for large area coating for solar energy or fuel cells and flip-chip applications. Research sized targets are also produced as well as custom sizes and alloys. All targets are analyzed using best demonstrated techniques including X-Ray Fluorescence (XRF), Glow Discharge Mass Spectrometry (GDMS), and Inductively Coupled Plasma (ICP). "Sputtering" allows for thin film deposition of an ultra high purity sputtering metallic or oxide material onto another solid substrate by the controlled removal and conversion of the target material into a directed gaseous/plasma phase through ionic bombardment. Besides rotary targets we can also provide targets outside in just about any size and shape, such as rectangular, annular, or oval targets. 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 nanoparticles . We also produce Cobalt as disc, granules, ingot, oxide pellets, oxide pieces, oxide powder, and rod. 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. 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".
