Sub-white fused alumina is developed on the basis of corundum smelting formed, with its alternative channel dense corundum castable made of iron and alternative white fused alumina, tabular alumina production skateboard, corundum brick, castable wear, are acquisition and use of dense white fused alumina and other significant effects. However, with the large-scale mass production, and market competition, combined with the traditional sub-white fused alumina from the bauxite refining directly inherent defects, causing the market sub-white fused alumina in the actual use of the detonation, powder and other unstable phenomenon. This can cause a number of alternative sub-white fused alumina white fused alumina products manufacturer had a doubt on the sub-white fused alumina, and even negative attitude.
