我厂白刚玉特点:

　　1.水分酸洗，白度高

　　2.黑点，水洗、沉淀后观察最上边一层，极少量黑点，不影响使用

　　3.用吸铁石吸粉料，无金属杂质

　　白刚玉微粉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、效率高、,热态性能稳定它硬度略高于棕刚玉，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.
