It is mainly composed of calcium carbonate (CaCO3). It can be obtained through mining natural limestone, marble, or chalk deposits. These raw materials are then processed to meet industrial requirements.
Physical Properties
Typically, industrial-grade calcium carbonate appears as a white powder with different particle sizes. Its particle size distribution can vary from relatively coarse to extremely fine, which affects its performance in different applications. It has a relatively high hardness and a stable chemical structure.
Production Process
The production process usually involves crushing, grinding, and classification of the raw materials. Different processing methods can be used to obtain calcium carbonate with specific particle sizes and properties. Chemical purification may also be carried out to remove impurities and improve the quality of the product.
