白刚玉是以*的铝氧粉为原料，经电熔冶炼而成，它具有颜色洁白、硬度高、韧性稍低、 纯度高、自锐性优、磨削力强、发热量小、*、耐酸碱腐蚀、耐高温、热稳定性好等特点，它不但是*的磨料磨具材料，且还是*研磨、抛光材料等，用它加工制成的磨具，还用于磨削高碳钢、高速钢及各种不锈钢

。它还广泛用于精密铸造、钢铁耐火、化工耐火、95电瓷、装饰瓷等各种陶瓷及日常生活用瓷，以及军工、电子等高科技行业。

White fused alumimum oxide is electrically fused in the furnance with high-grade alumina powder as raw materisls. It has higher hardness and slightly lower toughness than brown fused aluminium oxide ,characte-rize by its high purity,strong grinding ability,Abrasives tools made of it are suitable for grinding highspeed 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 ,et
