Ground Calcium Carbonate (GCC) Powder - Industrial Grade
1. Product Overview
Ground Calcium Carbonate (GCC) is a naturally occurring mineral obtained from high-purity
limestone or marble. It is mechanically ground into fine powder without changing its chemical
structure. GCC is widely used in various industrial applications due to its excellent physical and
chemical properties.
