Caustic Calcined Magnesite is made from raw magnesite, brucite and magnesium hydroxide re-extracted from seawater or brine by calcination in reverberatory furnaces, rotary kilns or boiling furnaces. It is light brown or white powder, odorless, tasteless and with high refractory insulation properties.
MgO content : From 70%min. to 96%min.
Dead Burned Magnesite is obtained by sintering selected raw magnesite ores or caustic calcined magnesite in shaft kilns at high temperatures. It has high temperature performance and is widely used in the production of refractory industry.
MgO content: 87%min. 90%min.92%min. 95%min. 97%min.
Fused Magnesite is made by electro-fusing selected A grade raw magnesite or high purity calcined magnesite grain in electric arc furnaces. It features by high purity, big crystalline size, dense structure, good corrosion resistance and thermal shock resistance.
