Understanding the Difference Between GCC and PCC

Ground Calcium Carbonate (GCC) and Precipitated Calcium Carbonate (PCC) are both widely used industrial minerals, but they are produced differently and suit different end uses.

GCC is made by crushing and grinding naturally occurring limestone. It offers good brightness, controlled particle size, and cost-effective performance as a filler in plastics, paints, paper, and construction materials.

PCC is chemically precipitated, which allows tighter control over particle morphology, purity, and surface chemistry. It is preferred where higher brightness, finer particles, or specialised functionality are required.

Choosing between GCC and PCC depends on brightness targets, rheology needs, binder demand, and cost. Our technical team can help match the right grade to your process.
