Calcium Carbonate

It is a white insoluble powder-like substance which occurs naturally in minerals, chalk, marble, limestone, calcite, shells, pearl, etc. It finds extensive usage in the manufacturing industry as a building material (marble), ingredient for quick lime and cement.​

Calcium carbonate is produced commercially in two different grades. Both grades compete industrially based primarily on particle size and the characteristics imparted to a product.

  1. Ground Calcium Carbonate – Produced via extraction and processing of naturally occurring deposits. GCC crystal shape is irregularly rhombohedral and has a broader size distribution.
  2. Precipitated Calcium Carbonate – Produced via chemical precipitation via a carbocation process or as a by-product of some bulk chemical processes. PCC crystal shape depends on the product and the product and the particles are more uniform and regular with a narrow size distribution.

PCC has smaller particles has a higher purity is less abrasive and tends to have higher brightness than GCC.

We, at Kaaren, make sure you get your hands on the fine calcium carbonate which you are looking for.
