Magnesia spinel bricks are refractory products made of periclase and magnesia alumina spinel ,which can improve the heat stability of common magnesia brick.

Features
1.Excellent Heat Stability.
2.Better Anti-stripping performance than direct bonded magnesia chrome brick.
3.Abrasion Resistant.
4.High Refractoriness Under Load.

Application
It’s mainly used for burning zone and transition zone of cement kiln, also some other industrial furnaces.
