点击图片查看大图多晶硅喷砂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，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 andcooling. It is white with the main crystal phase a-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.
