Calcium carbonate powder is a compound, the chemical formula is CaCO3, it is alkaline, basically insoluble in water, soluble in acid. It is a common substance on the earth and exists in rocks such as aragonite, calcite, chalk, limestone, marble and travertine. It is also the main component of animal bones and shells.
Heavy calcium carbonate is made by mechanically crushing natural calcite, marble, chalk and shells. Only physical changes occur in the entire production process, no chemical process.
Light calcium carbonate is also called precipitated calcium carbonate, colloidal calcium carbonate or activated calcium carbonate.
It is calcined limestone raw materials to generate lime and carbon dioxide, and then add water to digest the lime milk. The main component is calcium hydroxide. Then the carbon dioxide is introduced to carbonize the lime milk to form calcium carbonate precipitation. After a series of steps such as dehydration, drying and crushing, the final product is light calcium powder.
