Activity

Sintered plate corundum is a pure and thoroughly burnt without adding any additives such as MgO, B2O3, with a large crystalline, well-developed 伪- Al2O3 crystal structure with a content of over 99%. Plate crystal structure, small air holes and more closed air holes and the air pore rate is roughly equivalent to that of electro molten corundum, high purity, good volume stability, small refiring shrinkage, after high temperature treatment of material resistance or pouring materials has good thermal shock stability and bending strength, but the price is higher than other alumina.
Sintered plate rigid jade can be used as the main component for aluminum carbon, aluminum carbon, magnesium carbon, magnesium and aluminum carbon, magnesium spinel, aluminum chrome refractory brick, or as aluminum rich component introduced to high aluminum indefinite refractory materials, can be widely used in steel, casting, ceramics, the application in the steel industry almost covers the whole process of steel steelmaking.
