Calcium carbonate is used medicinally as a calcium supplement or as an antacid. It is also used for industrial purposes. Calcium carbonate is the most widely used mineral in the paper, plastics, paints and coatings industries. Hierarchical hollow calcium carbonate particles show a useful application as an anticancer drug carrier. It plays an essential role to catalyze alcoholysis of fats and oils.
