棕刚玉、黑刚玉、白刚玉、碳化硅统称金刚砂，是用矾土、碳素材料、铁屑三种原料在电炉中经过融化还原而制得的人造刚玉，故为此名。金刚砂主要化学成份是 AL2O3，其含量在94.5%-97%，另含有少量的Fe，Si，Ti等。

Brown corundum, black corundum, white corundum, silicon carbide known as carborundum, is made of alumina, carbon materials, scrap iron three kinds of raw materials in electric furnace melting reduction of artificial corundum, reason for this name.Emery main chemical composition is AL2O3, and its content from 94.5% to 94.5%, the other contains a small amount of Fe, Si, Ti, etc.

金刚砂的等级的划分：The level of silicon carbide

金刚砂主成分是氧化铝，分等级也就用氧化铝含量来区分，金刚砂氧化铝含量越低也就硬度越低了。韧性好比 SiC 高，显微硬度1800-2200kg/mm2，体积密度≥3.85g/cm3，耐高温，耐火度高达1850℃。

金刚砂的使用范围：The scope of application of silicon carbide
