Calcium Carbonate Powder

Calcium carbonate powder, a naturally occurring compound with the chemical formula CaCO₃, is one of the most widely used minerals globally. Derived from limestone, chalk, or marble, this fine white powder has applications spanning industries ranging from construction to healthcare, thanks to its unique properties and abundance.

In the construction sector, calcium carbonate powder serves as a key component in cement and mortar formulations. Its fine particle size enhances workability, reduces shrinkage, and improves the durability of concrete structures. Additionally, it acts as a cost-effective filler in plastics, rubber, and paints, boosting product strength while lowering production expenses. For instance, in the paper industry, it is used as a coating pigment to improve brightness and opacity, ensuring high-quality printing surfaces.
