Description and Uses
Magnesium carbonate is obtained mainly by mining the natural mineral magnesite. The trihydrate salt, MgCO3·3H2O, is prepared by mixing solutions of magnesium and carbonate ions in the presence of carbon dioxide.
Used in Pharmaceutical units as a Magnesium Salt, Heat Insulator and Refractor, Antacid. Also used in Cosmetics, inks, glass, drying agent, color retention agent and etc.
