Uses

 Calcium carbonate (CAS NO.471-34-1) is one of several important inorganic chemicals and is widely used in both its pure and its impure states. As marble chips, it is sold in many sizes as a filler for artificial stone, for the neutralization of acids, and for chicken grit. It is used to produce viscous solutions or dispersions, to impart body, improve consistency, or stabilize emulsions, including suspending and bodying agents, setting agents, jellying agents, bulking agents, stabilizers and thickeners.

Production

Most of Calcium carbonate (CAS NO.471-34-1) used in industry is extracted by mining or quarrying. Pure calcium carbonate can be produced from a pure quarried source (usually marble). Calcium oxide is prepared by calcining crude calcium carbonate.
