Products Description of Magnesium carbonate CAS#546-93-0

Magnesium carbonate (MgCO3, pKso=7.5-8.2), another important compound of magnesium, occurs naturally as magnesite,but the magnesium carbonate used in the United States is all synthetically manufactured. 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.
