The fused cast corundum brick has good high temperature volume stability and corrosion resistance.
The structure of α-Al2O3 fused cast bricks is dense and has certain resistance to glass melt erosion and erosion resistance.
β-Al2O3 fused cast bricks contain almost no glass phase, basically no shrinkage cavity, good thermal shock resistance, and high temperature resistance to alkali vapor stability.
α-β Al2O3 fused cast bricks have the characteristics of α-Al2O3 and β-Al2O3 fused cast bricks. The main crystal phases are directly combined, and the composition contains only a small amount of glass phase. The crystal structure is compact, the porosity is low, the high temperature wear resistance is good, the mechanical strength is high, and it has good high temperature resistance to alkali vapor stability.
