黑碳化硅是以石英砂，石油焦为主要原料，通过电阻炉高温冶炼而成，其硬度介于刚玉和金刚石之间，机械强度高于刚玉，性脆而锋利，具有一定的导电性和对热性。用其制作磨具，适应于加工抗张强度低的金属和非金属材料，如灰铸铁，有色金属，石材，皮革，橡胶等，还广泛用于耐火材料，如灰铸铁，有色金属，石材，皮革，橡胶，还广泛用于耐火材料，冶金添加剂。
Black silicon carbide
Black silicon carbide is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke as its main raw marterials .Its hardness is between fused alumina and synthetic diamond.Mechanical intensity of it is higher than fused alumina .It is brittle and sharp has electrical and heat conductivity in some degree.The abrasives made of it are suitable for working on cast iron,non-ferrous metal,rock, leather,rubber,etc.It is also broadly used as refractory material and metallurgical additive.
