Description

Description of White Fused Alumina:

White Fused Alumina uses first grade low sodium industrial alumina as raw material, which is melted at 2250℃ in a high-temperature electric arc furnace. It has the advantages of low sodium content, high purity, high temperature resistance, low porosity, large bulk density, good thermal stability, and goodacid and alkali corrosion resistance.

White Fused Alumina is the main raw material for the production of amorphous and shaped refractory materials, and it is the main raw material for the production of amorphous refractory materials such as large ladle castable,medium and high grade iron hook castable,prefabricated parts, and various corundum products such as corundum bricks and high temperature industrial kiln linings.
