Aluminum-magnesium spinel (magnesia-alumina spinel) refers to magnesium oxide and trialumina as raw materials, by artificial synthesis of spinel refractory raw materials. The raw material is rarely found in nature, and the industrial magnesia-aluminum spinel is all synthetic. Bauxite based sintered magnesia alumina spinel is made of high quality bauxite with Al2O3 content of more than 76% and high quality light burnt magnesia powder with MgO content of more than 95%, after multi-stage homogenization process, sintered at high temperature above 1800°C in ultra-high temperature tunnel kiln
Large volume density, high mineral phase content, good grain development, uniform structure and stable quality. Magnesium aluminum spinel has good corrosion resistance, corrosion, peeling ability, good slag resistance, abrasion resistance, thermal shock stability, high temperature resistance and other performance characteristics. It is the ideal raw material for producing magnesia alumina spinel brick, ladle lining brick, ladle castable and other refractory products for high temperature zone of cement rotary kiln. Magnesia aluminum spinel is widely used in refractory materials, iron and steel smelting, cement rotary kiln and glass industrial kiln
