What is Cobalt Carbonate used for?

Uses
Cobalt Carbonate, also known as spherocobaltite, is a mineral with chemical formula CoCO3. It is the carbonate salt of cobalt. It forms red trigonal crystals with specific gravity 4.13 which decompose on melting. Cobalt carbonate is insoluble in either cold or hot water but soluble in acids.
Cobalt carbonate is used in pottery glazes and may be found in pottery supply stores.
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.

What is the use of Cobalt carbonate?

Cobalt is a lustrous, silvery-blue metallic chemical element, symbol Co, atomic number of 27 and an atomic weight of 58.93.
Cobalt compounds are used as pigments in glass and ceramics. It is used as a drying agent for paints, varnishes and inks.
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.
Cobalt carbonate has the coloring application as it decomposes to cobalt oxide at high temperature. Cobalt carbonate tends to disperse better in a glaze but can produce blisters because of the CO2 gas presence at high temperature. Commercial grades of cobalt carbonate are the complex of carbonate and hydroxide such as cobalt carbonate hydroxide (1:1) (CAS RN: 12069-68-0), Cobalt carbonate hydroxide (2:3) (CAS RN: 12602-23-2), and cobalt carbonate hydroxide (2:3) monohydrate (CAS RN: 51839-24-8).

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
