Specifications and Applications of Cobalt (Co)
Properties:
Cobalt is a chemical element with the atomic number 27.
Cobalt is found in chemically combined form.
The cobalt is hard and solid with grayish color. Cobalt has a high boiling and melting points. At room temperature and standard pressure cobalt can barely be oxidized. But if cobalt is heated, a cobalt oxide is formed. The oxide from cobalt can be used in many useful applications and the material acquires various colors depending on Cobalts oxidation state.
Applications:
Cobalt works as a magnet like iron. To enhance the magnets cobalt is usually mixed with aluminum and nickel. Cobalt is vital in applications where high temperature exists (alloyed with other elements cobalt is utilized in gas turbine generators, jet turbines). Cobalt is noncorrosive hard metal that can be used in electroplating. Cobalt salts are used as a coloring of glass, pottery, enamels, porcelain, and paint. Radioactive cobalt-60 can be used in medicine as in cancer treatment, and in preserving food.
Cobalt and its alloys are also useful in lithium ion battery cathodes, prosthetic parts(hip and knee replacements), medical orthopedic implants. Works as oxidation catalyst.
