Heavy Calcium Carbonate

Product Name:	Heavy Calcium Carbonate
CAS RN.:
Molecular Formula:

Heavy Calcium Carbonate is processed from heavy calcite. WE have common heavy calcium carbonate (48μm above, 400 mesh down) and super fine heavy calcium carbonate (5-20μm). And different whiteness grades are available.

Heavy Calcium Carbonate granules are irregular with larger particle size and smaller specific surface area than Light Calcium Carbonate. They have low oil absorption and good fluidity; widely used in plastics, paper making, rubbers, chemical engineering, pharmacy, food, and feed industries.
