Magnesia alumina spinel is using industrial alumina or natural bauxite and high purity caustic magnesia powder as raw materials.It is an important aggregate used to enhance refractory properties.With the features of good erosion, abrasion, spalling and slagging resistance,perfect thermal shock resistance and high heat-resistance, it is the optimal material in producing magnesia-alumina spinel brick , ladle brick , ladle castable, etc.
