电熔 白色抛光粉末 抛光研磨白刚玉微粉F360#
电熔 白色抛光粉末 抛光研磨白刚玉微粉F360#以工业氧化铝粉为原料，于电弧中经2000度以上高温熔炼制成，经粉碎整形，磁选去铁，筛分成多种粒度，其质地致密、硬度高，粒形成球状，白刚玉适用于制造陶 瓷、树脂固结磨具以及研磨、抛光、喷砂、精密铸造等，还可用于制造高级耐火材料，代号“WA”于国际通用标准、国家标准一致，多数供出口，也有一定量供应国内用户。
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.
