Precipitated Calcium Carbonate. 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 carbonate minerals.

Generally speaking, the finished product size below 1500 mesh is generally produced by dry grinding process. For product size from 1500 to 2500 mesh can be produced by dry gridning process or wet gridning process. For products from 2500 to 6500 mesh, wet grinding process is usually appropriate for production. Ground calcium carbonate.
