Calcium Carbonate (CaCO₃) is an inorganic compound widely found in nature, primarily derived from natural minerals such as limestone and marble. Through processing techniques such as mechanical grinding or chemical precipitation, calcium carbonate can be produced in various particle sizes and properties to meet diverse industrial application needs.

Calcium carbonate is characterized by its chemical stability, high whiteness, abundant availability, and relatively low cost. Therefore, it has long been regarded as an essential basic industrial material. It is commonly used as a filler material and functional additive to improve the physical properties of materials, such as enhancing strength, rigidity, and dimensional stability. At the same time, it helps reduce raw material costs. Calcium carbonate has been widely applied across multiple industries, including plastics, rubber, coatings, paper, construction materials, and agriculture, making it an indispensable raw material in modern industrial production.
