Calcium carbonate is a chemical compound. It is a common substance found in rock in all parts of the world, and is the main component of shells of marine organisms, snails, pearls, and eggshells. It is the active ingredient in agricultural lime, and is usually the principal cause of hard water. Calcium carbonate is commonly used medicinally as a calcium supplement or as an antacid, but excessive consumption can be hazardous. The main use of calcium carbonate is in the construction industry. It is used in the oil industry in drilling fluids as a formation bridging and filtercake sealing agent and may also be used as a weighting material to increase the density of drilling fluids to control downhole pressures. It is widely used as an extender in paints and as a filler in plastics. It is also used in adhesives, sealants, and decorating fillers. Calcium carbonate is a common ingredient for many glazes/ceramics in its white powdered form.
