During the production process of tabular alumina, no additives are added, so it has high purity and relatively large grain hardness. Tabular alumina has high thermal load strength, low thermal shrinkage, high density and low air permeability, and particularly good wear resistance. There are many blocked small pores inside the grains of tabular corundum, so it has good thermal shock stability. Tabular alumina is resistant to chemical corrosion. Most alkalis and inorganic acids have no effect on tabular corundum, except hydrofluoric acid and phosphoric acid.
This series of advantages makes tabular alumina an ideal material for refractory raw materials. It can be used as aggregate or as an additive to other high-alumina amorphous refractory materials.
Tabular alumina can be used in the parts where fused corundum or white corundum is used to further improve the performance of refractory materials.
Tabular alumina can be used in kiln tools in the ceramic industry to improve its performance. For example, it improves the thermal shock stability and deformation resistance of ceramic rollers; and increases the life of saggers and shelves for high-temperature ceramics.
In addition, plate-like corundum can also be used as an insulator and as a catalyst carrier for high-temperature reactions with low porosity, high strength and high purity.
