Sintered magnesia-alumina spinel is sintered with high quality bauxite and magnesia through a multi-stage homogenization process at high temperatures above 1800℃. With erosion resistance, abrasion resistance, peeling ability, good slag resistance, good thermal shock stability, high temperature resistance and other performance characteristics.

Sintered magnesia-alumina spinel is an ideal raw material for high-temperature zones such as cement and lime rotary kilns, and refractory products such as ladle lining bricks and ladle castables.
