distribution as well as specific surface area (BET). PCC is a refined natural form of limestone using techniques. The purity can be increased to 99.9 % or 99.999 %, and grain size can be controlled in a range from submicron to more than 10 micron.5 Calcium carbonate occurs in different crystalline polymorphs at ambient pressure.

Precipitated Calcium Carbonate (PCC) | Minerals ...

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 …
