Product Description
High Quality White Corundum 5-8mm For Refractory
White fused corundum 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.
