High Purity Flakes Industrial White Powder Micronized Price Per Ton CaCO3 Calcium Carbonate
Calcium Carbonate Precipitated Calcium Carbonate Ground Calcium Carbonate Coated Calcium Carbonate
Our Calcium carbonate (CaCO3), widely found in calcite, limestone, marble, animal shells and bones, is a neutral inorganic white powder with high whiteness. Slightly soluble in water but soluble in hydrochloric acid, it stays chemically stable at room temperature and decomposes to release CO2 when exposed to acid. As an economical filler and white pigment, it expands material volume to cut costs while retaining mechanical performance, and serves as a vital raw material across construction and various industrial sectors.

Building and Construction
In the building and construction industry, calcium carbonate is a vital component in the production of cement, mortar, and concrete. It acts as a filler and improves the workability and strength of these materials. Limestone, a natural form of calcium carbonate, is also used as a building stone and in the manufacture of lime for mortar and plaster.

Paper Industry
In paper manufacturing, calcium carbonate is used as a filler and coating pigment. It enhances the brightness, opacity, and printability of paper, improving its overall quality. Precipitated calcium carbonate (PCC) is particularly favored in this industry due to its ability to provide a smooth, high-quality surface for printing.
Environmental Applications
Calcium carbonate plays a role in environmental applications, such as water treatment and soil remediation. It can neutralize acidic water and soil, improving their quality and supporting plant growth. Additionally, calcium carbonate is used in flue gas desulfurization processes to remove from industrial emissions, reducing air pollution.
