Cobalt Carbonate
Cobalt Carbonate is a rose-red to purplish powder with a metal content of approximately 46% cobalt by weight. It is an inorganic compound primarily used as a source of cobalt, either as a raw material in chemical synthesis or as a micronutrient in various formulations. It is slightly soluble in water and decomposes upon heating, releasing carbon dioxide and leaving cobalt oxide (CoO). Cobalt Carbonate is used in ceramics, catalysts, animal nutrition, batteries, and metal surface treatments. Its controlled release of cobalt makes it useful in both industrial and biological applications.
