白玉刚半导体喷砂用白刚玉磨料

白玉刚半导体喷砂用白刚玉磨料
白刚玉三高特点，适用于要求高的半导体喷砂：
1.高纯度：Al2O3含量高达99.2%以上
2.高清洁度，成型完整，极少量粉末。
磨料放入玻璃杯中加水搅拌，水溶液清澈透明，少量悬浮物
3.高堆积密度，颗粒圆度值低
白刚玉是以铝氧化粉为原料，经电熔提炼结晶而成， 纯度高、自锐性好、耐酸碱腐蚀、耐高温、磨削能力强、发热量小、、,热态性能稳定它硬度略棕刚玉，韧性稍低。用其制成磨具，适用于磨削高碳钢、高速钢及不锈钢等细粒度磨料还可以用于精密铸造和耐火材料。
White fused alumina was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling. It is white with the main crystal phase alpha-Al2O3.The white alumina produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved.
