Description

Calcium Carbonate CaCO3 Commerical Grade Dealers In Shree Vissnu Scientific Company Carbonic acid calcium salt (CaCO3). An odorless, tasteless powder or crystal that occurs in nature. Calcium carbonate is used therapeutically as a phosphate buffer in hemodialysis patients and as a calcium supplement. Calcium Carbonate is a 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.
