Product Description

Product Description

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.

The purity of Calcium Carbonate is upto 99%, very high whiteness and low metal content. Nowadays, Calcium carbonate is necessary material for many industries because it make save cost, improve usage of final product.
