How to Choose the Most Suitable Fused Zirconium Corundum Brick
The demand for fused zirconia corundum bricks without shrinkage casting has increased in recent years. Except for 41# fused zirconium corundum bricks, which are almost completely cast-free, the need for oxidation method 33# non-shrinkage fu...

Why Does the Quality of Zirconium Corundum Bricks Have an Effect on Glass Stones?
The mineral phase composition of fused zirconium corundum brick: corundum, oblique zircon, AZ eutectic and glass phase. Since corundum and oblique zircon are closely combined with each other, the eutectic structure is formed uniformly and d...

Raw Material and Process Flow of Fused Zirconium Corundum Brick
The fused zirconia corundum brick is mainly composed of zircon and industrial alumina, and a small amount of zirconium-rich sand (in order to increase the content of ZrO2) and soda ash (fused, Na2O can inhibit the formation of mullite and p...

Performance analysis of corundum brick
1. Fire resistance of corundum brick It can be seen from the binary phase diagram of Al2O3 - Cr2O3 that Al2O3 and Cr2O3 can form a continuous solid solution without eutectic. Therefore, the addition of Cr2O3 to the high-purity corundum mate...
