White Fused Alumina properties
(WA)White fused alumina / White Corundum is a high-grade refractory material, which made from high-quality alumina powder by melting above 2000 ℃ in the electric arc furnace and cooling, classified into different grain sizes. The white fused alumina is the main raw material for the production of unshaped and shaped refractory materials.
