白剛玉微粉概述：
白剛玉微粉性能：白色，較棕剛玉硬而脆，切削力較強，化學穩(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，抗張強度較大的材料。還可用做觸媒體，絕緣體以及精密鑄造砂等。
白剛玉微粉
Property:It is white and harder and more brittle than A.It features strong cutting force and steady chemical property and execllent insulation.
Usage:It can be used for making bonded and coated abrasive tools,wet or dry blasting.It is also suitable for superprecision grinding and polishing of crystal and electronic induxtry and making high quality refractory materials.It can be adopted for the grinding of the hard and strong bending strength materials such as chilled steel,alloy steel,high-speed and high carbon steel.Meanwhile,it can be used as catalyst carrier,insulator and presicion founding sand,etc.
