White fused alumina is the main starting material to produce high-grade unshaped and shaped refractories and is wide-used in the field of iron&steel industry, cement industry, ceramics, petrochemical industry, etc. It is the ideal starting material to produce the unshaped refractories such as large ladle castables, medium and high grade BF trough castables, gunning material to produce alumina products such as corundum sagger, refined porous plug bricks, monolithic lance&composite nozzle, lining material for high-temperature industrial furnaces, etc.
