What is Precipitated Calcium Carbonate? Precipitated calcium carbonate, or PCC, is a synthetic calcium carbonate product. It is derived from, and possesses, the same chemical formula (CaCO3) as natural calcium carbonate (limestone), but is chemically purer than natural limestone. PCC has a long commercial history.
