Tabular Corundum

What is tabular corundum

Tabular corundum is a kind of pure sintered corundum that does not add any additives such as MgO, B2O3, and so on. It has a coarse and well-developed α-Al2O3 crystal structure. The content of Al2O3 is more than 99%. . (According to the molecular structure, corundum can be divided into fine material, granular, flake, spherical, etc.)


  • high purity
  • high whiteness
  • low apparent porosity
  • low water absorption

Tabular corundum can be used as the main component in aluminum-carbon, aluminum-magnesium-carbon, magnesium-aluminum-carbon, magnesium spinel, aluminum-chromium refractory bricks; It can also be introduced into high-alumina amorphous refractory as a component of enriched alumina.

It can be widely used in steel, casting, ceramics and other industries, and its application in the steel industry covers almost the entire process of iron making and steelmaking.


High refractoriness, high corrosion resistance, high slag resistance, high thermal shock resistance, high strength, good toughness and chemical stability, high erosion resistance.

Packing information
