Magnesia Chromite Brick

Magnesia chromite bricks are fired at high temperature with magnesia and chromium concentrate as the main raw materials.Magnesia Chromite Brick has excellent thermal shock stability and resistance to repeated condensation and evaporation of alkali steam.

Characteristics:
1.Excellent thermal shock stability
2.Good resistance to alkali steam.
3.High cold crushing strength.

Application:
It is mainly used for central checker bricks and wall bricks in the regenerator of glass melting furnaces.
