Corundum Mullite Brick

Corundum mullite bricks are made of corundum and mullite as main raw materials and are fired at high temperature in an oxidizing atmosphere by adding appropriate amounts of alumina, silica ultrafine powder, and additives. The main crystal phases of corundum mullite bricks are corundum and mullite.

Advantages Of Corundum Mullite Bricks

1.High refractoriness and high refractoriness under load
2.Good chemical resistance to the acidic solution or molten slag.
3.Antioxidant. It will not react with O2, H2, CO, and other gases.
4.Good thermal stability and stable volume under high temperature
5.Good thermal shock resistance and not easy to peel off.
6.Excellent cold crushing strength and good wear resistance.

Corundum mullite bricks can be directly exposed to flames. They can be used as heat insulation linings for high-temperature industrial furnaces and working layers for other industrial high-temperature furnaces. They are mainly used in the petrochemical industry and synthetic ammonia gasification furnace and magnetic materials. In blast furnace, it is mainly used in the bottom, hearth, tuyere and iron notch of ceramic cup.
