white fused aluminium oxide is electrically fused in the furnace with high-grade alumina powder as raw materials. It has higher hardness and slightly lower toughness than brown fused aluminium oxide, characte-rized by its high purity, strong grinding ability,Abrasive tools made of it are suitable for grinding highspeed steel,high carton steel, etc.It also can used as materials for grinding and polishing precision-casting,spraying and coating,medium body for chemical industry, special ceramics and high-grade refractory materials,etc.
