白剛玉是以優(yōu)質(zhì)的鋁氧粉為原料，經(jīng)電熔冶煉而成，它具有顏色潔白、硬度高、韌性稍低、 純度高、自銳性優(yōu)、磨削力強、發(fā)熱量小、效率高、耐酸堿腐蝕、耐高溫、熱穩(wěn)定性好等特點，它不但是高級的磨料磨具材料，且還是高級研磨、拋光材料等，用它加工制成的磨具，還用于磨削高碳鋼、高速鋼及各種不銹鋼

。它還廣泛用于精密鑄造、鋼鐵耐火、化工耐火、95電瓷、裝飾瓷等各種陶瓷及日常生活用瓷，以及軍工、電子等高科技行業(yè)。

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 ,etc.
