Cobalt Carbonate CAS：513-79-1
Cobalt(II) carbonate (CoCO₃) is a reddish, paramagnetic solid that acts as an intermediate in the hydrometallurgical extraction of cobalt from ores. It serves both as an inorganic pigment and a precursor for catalyst synthesis. Found naturally as the rare mineral spherocobaltite (which has a red-to-pink hue), it is commonly produced industrially by precipitating cobalt sulfate solutions with sodium bicarbonate.

Cobalt(II) carbonate occurs naturally as the mineral sphaerocobaltite and has a wide range of industrial uses. It is used in ceramic manufacturing, serves as the base for cobalt-based pigments, acts as a catalyst in chemical reactions, and functions as a temperature indicator. Additionally, it is a precursor for various cobalt(II) salts and is used in animal feed supplements to boost the nutritional value of forage for livestock.
