Bauxite-grade Magnesia Alumina Spinel (MAS-70-30)
It's made of industrial alumina or natural superfine bauxite and high purity caustic calcined magnesia powder, sintered from rotary kiln with high temperature. It has the feather of high hardness, low thermal expansion etc.. it is the ideal raw material of ladle castable and magnesia spinel bricks. It is extensively applied to the lining of converter, glass kiln, open hearth, casting ladle, etc.
