cobalt processing, preparation of the metal for use in various products. Below 417 °C (783 °F), cobalt (Co) has a stable hexagonal closepacked crystal structure. At higher temperatures up to the melting point of 1,495 °C (2,723 °F), the stable form is facecentred cubic. The metal has 12 radioactive isotopes, none of which occurs naturally.
