Cobalt Metal (Co)
Used in:
1. Cobalt metal is mainly used for making alloys. Cobalt-based alloys are alloys made of cobalt and one or more of the chromium, tungsten, iron, and nickel groups. The wear resistance and cutting performance of tool steel containing a certain amount of cobalt can be significantly improved. High oxidation resistance can be achieved by using cobalt based alloys containing 20-27% chromium in the structural materials of aviation turbines without protecting the cladding.
2. Cobalt metal is also widely used in electroplating, glass, dyeing, medicine and medical treatment. Lithium cobalt oxide, made of lithium carbonate and cobalt oxide, is the most widely used high-energy battery cathode material in modern times.
3. Cobalt could also be used to make a nuclear weapon, a theoretical atomic or hydrogen bomb encased in a cobalt shell that would turn it into deadly radioactive dust when exploded.
