Features

Calcium carbonate light grade, also called calcium carbonate preciptated; it's produced by chemical synthetic process from calcium oxide and carbon dioxide and collect it from filtration and drying process.

Application

Precipitated light powder (CaCO3) is an important additive applied in many industries: ceramic industry, paint industry, paper industry, plastic industry, rubber industry, chemical industry... Depending on the whiteness, fineness, CaO containing and impurities in the powder, we use them for different purposes.
