        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.
