Dead Burned Magnesite and Caustic Calcined Magnesite

The diffirence between Dead Burned Magnesite and Caustic Calcined Magnesite

Dead Burned magnesite is burned at 1800℃ in rotary furnace, carbon dioxide is completely escaped, magnesium oxide formed a dense block of periclase. It is also called sintered magnesia, due to high temperature resistance, it is mainly used in refractories.  

Caustic calcined magnesite is produced by calcined the raw magnesite at 900℃.  Due to its high reactiry, widely used in water treatment, flue gas treatment,  abrasive industry, magnesium salt production, feed industry, magnesium fertilizer in agriculture and so on.
