What is Cobalt Carbonate?

Cobalt Carbonate is the inorganic compound with the formula CoCO3. This reddish paramagnetic solid is an intermediate in the hydrometallurgical purification of cobalt from its ores. It is an inorganic pigment, and a precursor to catalysts. Commercially available pale violet basic cobalt carbonate, with the formula CoCO3(Co(OH)x(H2O)y (CAS 12069-68-0).
Properties
Cobalt Carbonate is prepared by heating cobaltous sulfate with a solution of sodium bicarbonate.
The resulting CoO converts reversibly to Co3O4 at high temperatures.[3] Like most transition metal carbonates, cobalt carbonate is insoluble in water but is readily attacked by mineral acids
Uses
Cobalt Carbonate is a precursor to cobalt carbonyl and various cobalt salts. It is a component of dietary supplements since cobalt is an essential element. It is an precursor to blue pottery glazes, famously in the case of Delftware.
