白刚玉微粉概述：
白刚玉微粉性能：白色，较棕刚玉硬而脆，切削力较强，化学稳定性好，具有很好的绝缘性。
适用范围：可做固及涂附磨具，湿式或干或喷射砂，适合晶体，电子行业的超精研磨和抛光及制做高级耐火材料等。适合加工淬火钢，合金钢，高速钢，高碳钢等硬度较硬，抗张强度较大的材料。还可用做触媒体，绝缘体以及精密铸造砂等。
白刚玉微粉
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.
