magnesia-alumina spinel

Magnesia Alumia Spinel
Sintered bauxite-based magnesia-alumina spinel chooses the high-quality bauxite and high-grade light-burned magnesia. It’s sintered at high temperature after complicatedly homogenized processes. With the features of good erosion ,abrasion, spalling and slagging resistance, perfect thermal shock resistance and high heat resistance, it is the optimal in producing magnesia alumina spinel brick, ladle bricks, laddle castable, etc.
