Fused Magnesite is produced in the Rotary Kiln by sintering raw magnesite at a controlled temperature and its chemically inactive. Its consume almost exclusively in the production of Refractory Field.
Above 900 °C, the material loses its reactive crystalline structure and reverts to the chemically inert ‘dead-burnt’ product- which is preferred for use in refractory materials such as furnace linings. Magnesite can also be used as a binder in flooring material (magnesite screed).
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.
