Calcium carbonate has a wide range of applications across different industries:
Paints and Coatings
It’s employed as a pigment and filler in paints, coatings, and primers to improve coverage, durability, and viscosity.
Paper Industry
It’s used as a filler and coating pigment in the production of paper and cardboard to improve brightness, opacity, and smoothness.
Plastics
Calcium carbonate is added to plastics as a filler to improve mechanical properties, reduce costs, and enhance dimensional stability.
Construction Materials
Calcium carbonate is used in the production of concrete, mortar, and asphalt as an aggregate and filler to improve strength, durability, and resistance to weathering.
Adhesives and Sealants
It’s utilized as a filler in adhesives and sealants to improve viscosity, adhesion, and rheological properties.
Pharmaceuticals
Calcium carbonate is used as a calcium supplement in pharmaceuticals and as an antacid to relieve heartburn, acid indigestion, and upset stomach.
Food and Beverages
It’s used as a dietary supplement in food and beverages, as well as a food additive (E170) in products such as baking powder, cake mixes, and chewing gum.
Environmental Remediation
