Product Overview
Calcite is a natural crystalline polymorph of calcium carbonate characterized by rhombohedral crystal cleavage. Sourced from crystalline mineral deposits in southern Rajasthan, raw stone is pulverized and air-classified to narrow particle size distributions at our Pindwara unit.
Due to its natural crystal structure, low acid-insoluble abrasive content, and uniform dispersion, ground calcite powder is widely used in polymer compounding, architectural coatings, and industrial paints where screw wear must be minimized and consistent optical properties are needed.
