Calcium Carbonate
Product Details
Calcium carbonate is a chemical compound with the formula CaCO,.The thermodynamically stable form of CaCO, under normal conditions is hexagonal β-CaCO,.Calcite, aragonite and vaterite are pure calcium carbonate minerals. Industrially important source rocks which are predominantly calcium carbonate include limestone, chalk, marble and travertine.
