Caustic CalcinedMagnesite (CCM) is a highly reactive form of magnesium oxide produced by calcining or burning crude magnesite at relatively low temperatures (>1000°C). Reactive magnesia is also variously known as caustic calcined magnesia, caustic magnesia or CCM. The temperature of firing has a greater influence on reactivity than grind size.
Reactive magnesia is essentially amorphous magnesia with low lattice energy and is made at low temperatures and finely ground.
Low-purity CCM is used in industrial applications such as waste water treatment. High-purity CCM is used in pharmaceuticals, cattle feed supplement, fertilizer, adhesive, Tyre.
Caustic calcined magnesia is available in a wide range of different purities (typically 85-95% MgO) and particle sizes.
