The content of alumina content of corundum brick is more than 90%.High pressure resistance at room temperature (up to 340MPa).High rul start temperature (greater than 1700 ℃).Good chemical stability, strong resistance to acid or alkaline slag, metal and glass liquid.The thermal shock stability is related to the structure, the corrosion resistance of compact products is good, but the thermal shock stability is poor.It is divided into sintered corundum brick and fused zirconium corundum brick.Sintered alumina and fused alumina can be used as raw materials or alumina clinker with high Al2O3/SiO2 ratio and sintered alumina respectively.It can also be made from phosphoric acid or other adhesive without burning corundum bricks.

 My company development and production of corundum series of products based on high-quality fused corundum or sintered corundum as raw material, add high purity oxide by high pressure high temperature burning, senior form of refractory products, has excellent abrasion resistance to acid at high temperature and erosion resistance, and has high temperature strength, is a large blast furnace, glass kiln, high-temperature kiln cement, ceramic kiln, blast furnace and blast furnace hot blast stove, furnace refining furnace, sliding water apparatus, glass furnace, and petrochemical industrial furnaces, etc.High quality lining materials such as chemical colored kilns.

High quality refractory Corundum-Mullite bricks 

Corundum mullite bricks are made from compact fused corundum, alumina powder and so on.The purity of corundum sand and the technological formula are used to meet the requirements of different corundum products. 

Properties of fused alumina mullite brick:

1. Heavy materials have good compactness, high compressive strength, corrosion resistance of various corrosive gases, good thermal shock stability, good thermal conductivity and wear resistance.

2. The material has uniform internal structure, high compressive strength, corrosion resistance, heat resistance, shock resistance, oxidation resistance, high operating temperature and low thermal conductivity.
