White Tabular Alumina

White Tabular Alumina

Purity: ≥ 99% Al₂O₃


Shape: Flat or sheet-like

Property: Sintered corundum

Crystal structure: Hexagonal crystal system with high hardness and high melting point

Applications: Grinding and grinding tools, cutting tools, high-temperature and refractory applications, electronic ceramics


White tabular alumina is a kind of sintered corundum, which is white in color and has the advantages of coarse crystals and high purity. The crystal contains many circular closed pores and fewer open pores. Because it does not add any additives and has high purity, our white tabular alumina has the characteristics of high melting point, high grain hardness, high thermal load strength, low thermal shrinkage, high density, low air permeability, and good wear resistance. In particular, there are many small closed pores in the crystal grains, which makes the thermal shock stability good.

Our white tabular alumina is an ideal refractory raw material. It can be used as aggregate in a variety of refractory materials and can also be added to other high-alumina amorphous refractory materials.

Yafeite white tabular alumina has a wide range of applications, including steel, foundry, petrochemical, ceramics and incineration industries, and can also be used as electrical insulators, kiln furniture and catalyst carriers.
