Calcium carbonate

Calcium_carbonate_500

CaCO3 or CCaO3

Calcium carbonate appears as white, odorless powder or colorless crystals. Practically insoluble in water. Occurs extensive in rocks world-wide. Ground calcium carbonate (CAS: 1317-65-3) results directly from the mining of limestone. The extraction process keeps the carbonate very close to its original state of purity and delivers a finely ground product either in dry or slurry form. Precipitated calcium carbonate (CAS: 471-34-1) is produced industrially by the decomposition of limestone to calcium oxide followed by subsequent recarbonization or as a by-product of the Solvay process (which is used to make sodium carbonate). Precipitated calcium carbonate is purer than ground calcium carbonate and has different (and tailorable) handling properties.

Calcium carbonate is a calcium salt with formula CCaO3. It has a role as an antacid, a food colouring, a food firming agent and a fertilizer. It is a calcium salt, a carbonate salt and a one-carbon compound.Calcium carbonate is a calcium salt with formula CCaO3.
