Introduction to ultra-high temperature quick-fired tabular corundum:
Plate-like crystal structure, small pores and more closed pores and porosity is roughly the same as electrofused corundum, high purity, good volume stability, extremely small re-sintering shrinkage, used to produce refractory materials or castables after high temperature treatment has good thermal shock stability and flexural strength, but the price is higher than other alumina. High refractory; High corrosion resistance; High erosion resistance; High thermal shock stability; High strength and good toughness; Chemically stable. Plate corundum is a pure, sintered corundum that is completely shrunk without adding any additives such as MgO and B2O3, and has a α-Al2O3 crystal structure with coarse crystals and good development. Plate-like crystal structure, small pores and more closed pores, and the porosity is roughly the same as that of electrofused corundum, high purity, good volume stability, and minimal re-sintering shrinkage, which is used to produce refractory materials or castables with good thermal shock stability and flexural strength after high temperature treatment.
