Magnesia-Alumina Spinel Brick is in order to improve the heat stability of magnesia brick, add alumina oxide in ingredient to generate the magnesia brick which the main material is magnesia-alumina spinel. The advantage of magnesia-alumina spinel brick: good heat stability, in the process of use, it will have reaction with clinker and produce a thin layer of calcium aluminate maskant, which makes the liquid not easy to penetrate, its anti-stripping performance is better than the direct bonded magnesia chrome brick.

Characteristics of Magnesia Alumina Spinel Brick

1. High melting point
2. Small thermal expansion
3. Low thermal stress
4. Good thermal shock stability
5. Stable chemical properties
6. Strong resistance to basic slag

Application of Magnesia-Alumina Spinel Brick

1. The magnesia-alumina spinel can be used in the cement kiln, not only avoid the chrome pollution, and has good anti-stripping performance.
2. 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.
