Tabular corundum is suitable for the kiln mouth and coal injection pipe of large cement kilns. This castable possesses excellent spalling resistance, sufficient refractoriness, high-temperature strength, mechanical strength, thermal shock stability, and alkali resistance. Tabular corundum is a pure, sintered corundum without any additives such as MgO or B2O3, exhibiting a coarse-grained, well-developed α-Al2O3 crystal structure. Its plate-like crystal structure results in small pores and a high proportion of closed pores, with a porosity roughly equivalent to that of fused corundum. It boasts high purity, good volume stability, and minimal re-firing shrinkage. Refractory materials or castables produced with this material exhibit excellent thermal shock stability and flexural strength after high-temperature treatment, but at a higher price than other alumina materials.
