CachedActually, Magnesia alumina spinel brick produced from magnesia and spinel are commonly called magnesia spinel bricks or periclase spinel bricks. The reason why magnesia alumina spinel bricks were developed is that the thermal stability of magnesia bricks needed to be improved. Magnesia alumina spinel brick is featured with good thermal stability, low thermal expansion, high melting point and stable chemical properties, and has strong resistance to alkaline slag.
