Micronized Calcite Powder

Micronized Calcite Powder is the most refined form of natural calcium carbonate offered by Raviraj Minerals. Calcite is the most stable polymorph of calcium carbonate, and through our advanced micronization processes, we fracture the mineral crystalline structure down to incredibly precise specifications (10 microns). This results in a powder of outstanding purity (96%), unparalleled optical brightness (97% whiteness), and an exceptionally smooth, uniform particle profile. The high refractive index of calcite, coupled with its ultra-fine dispersion capability, makes it a premium functional extender. It is extensively utilized in the formulations of high-quality emulsion paints, providing tremendous hiding power and significantly reducing the demand for expensive Titanium Dioxide. Because it is chemically inert, it ensures the long-term color stability and weatherability of the applied coating. Furthermore, Micronized Calcite is a critical additive in the manufacture of high-voltage PVC cables and advanced color masterbatches. Its lack of coarse particles ensures no structural weaknesses or electrical fault points are introduced into the wire insulation. It provides excellent thermal stability, promotes a high melt-flow index during extrusion, and guarantees an immaculately smooth surface finish on all thermoplastic products.
