Precipitated Calcium Carbonate (PCC) is synthetic calcium carbonate. It is white ultra fine crystalline powder having consistent Particle Size Distribution and Excellent dispersibility.

High Purity lime stone is calcined in Lime Kiln to produce quick lime which is slaked and further carbonated to produce PCC slurry, which is filtered and dried to produce pure white PCC Powder.

Activated Calcium Carbonate is produced by surface coating the Precipitated Calcium Carbonate slurry with Fatty Acids (Stearic Acid) and Titanate Coupling Agent. Filtering and drying of the coated PCC slurry to produce ACC Powder.
The particle size, as well as the crystal form, is controlled by temperature, concentration of reactants and time.
