Calcite Powder, also known as Calcium Carbonate (CaCO₃), is a high-purity, naturally occurring mineral powder widely utilized in industrial manufacturing and processing. With a chemical composition comprising primarily of 90–99% calcium carbonate, trace impurities like MgO, Fe₂O₃, SiO₂, and Al₂O₃, this fine white powder exhibits excellent whiteness, a Mohs hardness of 3, and a specific gravity around 2.7. Insoluble in water yet soluble in dilute acids, Calcite Powder is pH neutral to alkaline (~9 in suspension). It serves as a versatile raw material and functional additive across multiple industry sectors, including plastics, paints, rubber, paper, construction, pharmaceuticals, food, and agriculture. Its applications range from acting as a filler to enhance rigidity and reduce production costs in plastics, to serving as a brightness and opacity enhancer in paper manufacturing. Furthermore, it is used as a soil conditioner to optimize agricultural productivity and as a pH stabilizer in various formulations. The product's consistent particle size and chemical purity ensure superior performance tailored to specific industrial needs, making the Calcite Powder an essential commodity for B2B buyers seeking a reliable calcium carbonate source.
