Bauxite based Sintered Magnesium Aluminum Spinel

Bauxite based Sintered Magnesium Aluminum Spinel is made from high-quality bauxite and high-quality magnesium oxide, adopting a unique technique and sintering at high temperature above 1800 ° C. It has the characteristics of strong corrosion resistance, good slag resistance, high thermal vibration stability and high temperature resistance. Compared with the current market products, it has higher strength and bulk density, lower porosity and water absorption, so it has better high temperature performance. It is the ideal raw material for refractory products such as Magnesium Aluminum Spinel bricks, ladle lining bricks, ladle castables which are used for cement rotary kiln, lime kiln and other high temperature used place.
