Precipitated Calcium Carbonate (PCC) is also known as purified, refined or synthetic calcium carbonate. PCC has the same chemical formula as other types of calcium carbonate, viz. limestone, marble and chalk i.e. CaCO3. The calcium, carbon and oxygen atoms can arrange themselves in three different ways, to form three different calcium carbonate minerals. The most common arrangement for both precipitated and ground calcium carbonates is the hexagonal form known as calcite. A number of different calcite crystal forms are possible: scalenohedral, rhombohedral and prismatic.
PCC is synthetically processed from naturally occurring high grade lime stone. The product has a major advantage due to its availability in different bulk densities from 0.40 gms/cc to 0.9 gms/cc, with dazzling white color with fluffy characteristics.The purity of the product is around 98.0 % as CaCO3.
PCC is available in Uncoated and Coated specifications. The Coated PCC is also known as Activated Calcium Carbonate.
