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