Magnesia alumina spinel brick introduction

Mgo-alumina spinel Brick detail

Magnesia alumina spinel brick is developed by Chinese scientist based on China’s natural resources that we have much alumina in China. Mg-Al brick’s main crystallization is periclase, and magnesia-alumina spinel is its matrix. Raw material is magnesite and industrial alumina.

Magnesia alumina spinel brick features

Magnesia alumina spinel brick has low linear expansion coefficient, apparent porosity below 9%, high mechanical strength, strong slag corrosion resistance, good anti-creep resistance, best thermal stability and excellent refractoriness under load.
