Cobalt Metal

Cobalt is a hard silverfish metal that is useful in jewelry making and even vitamins. With it’s varied usefulness it has become something that we all interact with on a daily basis.

Product Definition

Cobalt (Co) as a free element is generated by a process called reductive smelting. In this form it is a hard, silverish metal. Cobalt is ferromagnetic and has a specific gravity of 8.9. Small amounts of Cobalt compounds are found in rocks, plants and animals. Cobalt is frequently associated with nickel and both of these elements can be found in meteoric iron. Metallic Cobalt has two crystallographic structures, which are hcp and fcc. Cobalt is protected from oxidation by a passivating oxide film which makes it a weakly reducing metal. At regular temperatures Cobalt reacts slowly to mineral acids.
