Sintered Magnesia-Alumina Spinel
Sintered magnesia-alumina spinel is produced from high-quality bauxite and magnesia through high-temperature sintering above 1800°C. It features excellent erosion resistance, abrasion resistance, slag resistance, thermal shock stability, and high-temperature performance. As an important refractory raw material, it is widely used in cement and lime rotary kilns, ladle lining bricks, ladle castables, and other high-temperature refractory applications.
