Calcium carbonate is an inorganic compound with the chemical formula of CaCO3, commonly known as limestone, limestone, stone powder, etc. Calcium carbonate is alkaline, basically insoluble in water and soluble in hydrochloric acid. It is one of the common substances on the earth. It exists in aragonite, calcite, chalk, limestone, marble, travertine and other rocks. It is also the main component of some animal bones or shells. Calcium carbonate is also an important building material, which is widely used in industry.

2. Plastic manufacture: As the framwork in plastic products, keeping stablity of the products, strengthen the products, keeing surface smoothly. Since the calcium carbonate is hight white, it can place the expensive the white ployethylene, for whitening the plastic products.
3. Paper making: Whitening the paper, and as the fller, can reducing the pulp, for saving the cost etc.
