    白剛玉微粉的硬度略高于棕剛玉,是用含高純度Al2O3鋁氧粉在電弧爐中熔融結晶而成,在經過電熔提煉結晶而成,除了在純度上很高之外,在自銳性上也比較好,耐酸堿腐蝕等性能也都表現的很好,在熱態性能上很穩定;一般白剛玉微粉中Al2O3的含量在98.5%以上,Na2O的含量在.0.6%以下??勺龉探Y構及涂附磨具,濕式或干式噴射砂,適合晶體、電子行業的超精研磨和拋光及制作高級耐火材料等。由于白剛玉Al2O3粉中的Na2O受熱后蒸發,韌性相比來說差一些,因此可用在各式噴砂和研光作業、電視屏幕噴砂、硅切割、精密鑄造用型砂、高級耐火材料及其它的添加劑。

    另外,從硬度上來看白剛玉微粉也是比其他的產品高很多,我們畢竟需要對整個產品的韌性、磨削能力都做很好的分析,很多人都不知道白剛玉微粉的穩定性如何?其實,在現有市場中所能夠提供的都是穩定性比較好,在選擇的時候一定要看看這些基本的優勢,現在白剛玉微粉就是具備這樣的優勢在市場中才銷售的更好,而在國內也是有不少廠家在生產加工,整體的質量也都是很不錯,也可以滿足國內一部分市場。
