PCC stands for Precipitated Calcium Carbonate—also known as purified, refined or synthetic calcium carbonate. It has the same chemical formula as other types of calcium carbonate, such as limestone, marble and chalk: CaCO3. The calcium, carbon and oxygen atoms can arrange themselves in three different ways, to form three different calcium ...

Hydrated (or slaked) lime is a dry powder, putty or slurry produced in a hydrator by reacting quicklime with water. In the United States, most lime is produced as quicklime (about 85 percent). Lime can also be produced from other calcareous materials — such as aragonite, chalk, coral, marble and shell — and as a byproduct in paper mills ...
