棕剛玉、黑剛玉、白剛玉、碳化硅統(tǒng)稱金剛砂，是用礬土、碳素材料、鐵屑三種原料在電爐中經(jīng)過融化還原而制得的人造剛玉，故為此名。金剛砂主要化學成份是 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.

金剛砂的等級的劃分：The level of silicon carbide

金剛砂主成分是氧化鋁，分等級也就用氧化鋁含量來區(qū)分，金剛砂氧化鋁含量越低也就硬度越低了。韌性好比 SiC 高，顯微硬度1800-2200kg/mm2，體積密度≥3.85g/cm3，耐高溫，耐火度高達1850℃。

金剛砂的使用范圍：The scope of application of silicon carbide

1.噴砂——硬度適中，堆積密度高，無游離二氧化硅，比重大，韌性好，是理想的“環(huán)?！毙蛧娚安牧希瑥V泛應用于鋁型材，銅型材玻璃，水洗牛仔服精密模具等領域；

1. Sandblasting, moderate hardness, high packing density, no free silica, than major, good toughness and is the ideal "environmental protection" type sand blasting materials, widely used in aluminum, copper profile glass, washing jeans precision molds, and other fields;

2.自由研磨——研磨級磨料，應用于顯象管、光學玻璃、單晶硅、鏡片、鐘表用玻璃、水晶玻璃、玉器等領域的自由研磨，是國內(nèi)普遍采用的高級研磨材料；

2. The free abrasive, abrasive abrasive, applied to the tube, optical glass, monocrystalline silicon, lenses, clocks with glass, crystal glass, jade in areas such as free grinding, grinding is adopted widely in the domestic advanced materials;

3.樹脂磨具——磨料具有顏色合適、硬度好、有韌性、合適的顆粒斷面類型和刃口保持度，應用于樹脂磨具，效果理想；

3. The resin abrasive, abrasive has color appropriate, good hardness and toughness, suitable particle cross section type and keeping degree blade, used in resin abrasive, effect is ideal;
