details

Sintered Magnesia Alumina Spinel is made by high purity industrial alumina and magnesia. through multi-stage homogenization process, and sintered at ultra high temperature in shaft kiln. The product has characters of high bulk density, high level of spinel phase, well developed crystal, uniform microstructure and consistent properties.
it has great erosion resistance, anti-spalling and thermal shock resistance, and can be applied for refractory products as bricks, castables forladle lining, cement rotary kiln,glass furnace and so on .
