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.; Limestone is an odorless, white to tan powder.; Limestone (calcium carbonate) that has been recrystallized by metamorphism and is capable of taking a polish. Practically insoluble in water Molecular Formula: CaCO3;CaCO3;CaCO3;CCaO3 IUPAC Name: calcium;carbonate SMILES: C(=O)([O-])[O-].[Ca+2] Alfa Chemistry Materials product group: Glass Manufacturer data sheet |
