厂家供应180目白刚玉磨料
1. 白刚玉磨料:
白刚玉磨料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.
