Product Details

Magnesia alumina spinel brick is a kind of alkaline refractory product with periclase as main phase and magnesia-alumina spinel clinker as basic material. The product is of good temperature vibration, good strength and volume stability in high temperature environment.


  • The magnesia alumina spinel bricks can be used in the cement kiln, not only avoid the chrome pollution, and has good anti-stripping performance.
  • It can be used in refractory carstables for ladles, which greatly improve the anti-erosion ability. It is widely applied to steel-making refractory material. The preparation of high quality pre-synthertic spinel provide a new material for amorphous  and fixed high purity refractory.
