Ground Calcium Carbonate is a powder material obtained from calcite, marble, limestone, chalk, alabaster and other natural minerals as raw materials, processed by mechanical grinding.

In recent years, surface modification is one of the most active and fastest developing technologies in the field of non-metallic mineral powder processing, and it is also an important means to improve its application performance, expand the market and consumption. Therefore, it has received much attention from the non-metallic mineral powder industry and downstream application industries.
