Tabular Alumina (also called tabular Corundum) has been widely used in high-performance refractory materials for steel, foundry, petrochemical, and ceramics. It is a great high pure sintered α-Al2O3 materials that has been fully densified by rapid-sintering (at temperatures over 1900°C) without the use of sintering aids.

After heat treatment, the 18-20 mm pellets are crushed or ground to obtain tabular alumina of various sizes. The typical properties of tabular alumina are:

  • Chemical inertness.
  • High-melting point: 2000 ºC.
  • Low water absorption.
  • High thermal conductivity.
  • Good thermal shock resistance.
  • Excellent thermal volume stability.
  • High mechanical strength and abrasion resistance.


Tabular Alumina is used in a variety of industries such as steel, foundry, cement, petrochemical, chemical and ceramic.
