Caustic Calcined Magnesite (CCM) is a highly reactive form of magnesium oxide produced by calcining or burning crude magnesite at relatively low temperatures (>1000 °C). Applications for caustic calcined magnesia include water treatment and in production of feed stock, fertilizers, and some cosmetics.
