白刚玉(white fused alumina) FEPA#12

白刚玉是以优质铝氧化粉为原料,经电熔提炼结晶而成, 纯度高, 自锐性好, 耐酸碱腐蚀, 耐高温, 热态性能稳定它硬度略高于棕刚玉,韧性稍低,纯度高, 自锐性好, 磨削能力强, 发热量小, 效率高, 耐酸碱腐蚀, 耐高温热稳定性好。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高级耐火材料。

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.
