Magnesia Alumina spinel brick 
The brick is made from high purity magnesia sand and fused magnesia as raw materials and added with fused spinel, by highly pressed and fired at high temperature. The brick has features as follow: 1.excellent toughness at high temperature, the spalling damage is not easy to happen during drying kiln and using. 2. Excellent coat formed in burning zone, and normal coat damage does not spall. 3. Excellent strength and thermal shock resistance. 4. excellent anti-erosion and wear resistance performance . The product applies in burning zone.
