白剛玉概述：
　　白剛玉性能：白色，較棕剛玉硬而脆，切削力較強(qiáng)，化學(xué)穩(wěn)定性好，具有很好的絕緣性。
　　適用范圍：可做固及涂附磨具，濕式或干或噴射砂，適合晶體，電子行業(yè)的超精研磨和拋光及制做高級(jí)耐火材料等。適合加工淬火鋼，合金鋼，高速鋼，高碳鋼等硬度較硬，抗張強(qiáng)度較大的材料。還可用做觸媒體，絕緣體以及精密鑄造砂等。

　　Property:It is white andharder and more brittle than A.It features strong cutting force and steadychemical property and execllent insulation.
　　Usage:It can be used formaking bonded and coated abrasive tools,wet or dry blasting.It is also suitablefor superprecision grinding and polishing of crystal and electronic induxtryand making high quality refractory materials.It can be adopted for the grindingof the hard and strong bending strength materials such as chilled steel,alloysteel,high-speed and high carbon steel.Meanwhile,it can be used as catalystcarrier,insulator and presicion founding sand,etc.
