White Corundum 5-8mm for Refractory Aggregate

Al2O3 white electrocorundum refractory, a kind of high-grade refractory, was made from the high-quality alumina by melting above 2000 in the electric arc furnace and cooling. It is white with the main crystal phase alpha-Al2O3. The white alumina produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved.

Outstanding features are small crystal size, impact resistance, if the use of a self-grinding machine processing broken, most of the particles are spherical particles, dry clean surface, easy to bond agent.

Al2O3 white fused alumina compound refractory material is a optimal refractory material to make refractory bricks in ladles and fluidized bed furnaces in casting and foundry industries.
