1. Ground calcium carbonate introduction :

Calcium carbonate is an inorganic compound, commonly known as limestone, Greystone, stone powder, marble, calcite, alkaline, soluble in acid, Basically insoluble in water.
Heavy calcium carbonate, simply called heavy calcium, is a white powder made of fine calcite.Its chief composition is CaCO3. It displays such properties as whiteness, purity, soft color and stability in chemical composition. Therefore it is a very good filling widely used in industry.

2. Ground calcium carbonate Physical Properties :

Composition    CaCO3    Density(g/cm3)    Hardness    Whiteness    PH       Moisture content
Content%         70-98          2.7-4.5             2.5-3.5          84-97        8-9        < 0.5

3. Ground calcium carbonate usage :

Heavy calcium is widely used in daily chemical industry as fillings in artificial bricks, rubber, plastic, papermaking, coating, paint, printing ink, electric cable, food, medicine, spinning and weaving ,fodder and tooth paste, etc. lt can help to increase the volume of the products and reduce the costs.
