耐火材料电熔白刚玉微粉

白刚玉微粉是用**的一级白刚玉块通过破碎、球磨、酸洗、水洗、分级、筛松、检验、包装等数十道工序严格加工生产而成的白刚玉制品。其具有纯度高、体密大、耐高温、耐磨削，是理想的削磨抛光、耐火电瓷、精密铸造等行业不可缺少的材料。

The white fused alumina micro-powderis made from the high quality first-class white fused aluminablocks through dozens of strict working procedures, like crushing,ball-milling, acid-cleaning, water-cleaning, classification,sifting & selecting，testing，packing and so on. It ownsproperties as follows: high purity, high bulk density,high-temperature resistant, wear resistant, etc., and there fore,serves as the indispensable and ideal materials form manyindustries, such as grinding and polishing, refractoryelectric-porcelain and precision pasting.
