Cobalt foils are produced from cast ingots for use in coating and thin film Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes including Ultra High Purity (99.9+%) thin-film foil, 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.
Physical and chemical properties:
Cobalt is a shiny steel-gray metal, relatively hard and brittle, ferromagnetic, and its magnetism disappears when heated to 1150℃. The valence of cobalt is +2 and +3. It does not react with water at room temperature and is also stable in humid air. Cobalt is an important raw material for the production of heat-resistant alloys, hard alloys, corrosion-resistant alloys, magnetic alloys and various cobalt salts.
