黑碳化硅基礎(chǔ)知識

黑碳化硅是以石英砂,石油焦為主要原料,通過電阻爐高溫冶煉而成

黑碳化硅是以石英砂，石油焦為主要原料，通過電阻爐高溫冶煉而成，其硬度介于剛玉和金剛石之 間，機(jī)械強(qiáng)度高于剛玉，性脆而鋒利。具有一定的導(dǎo)電性和導(dǎo)熱性。用其制作磨具，使用于加工抗 張強(qiáng)度低的金屬和非金屬材料。如灰鑄鐵，有色金屬，石材，皮革，橡等。還廣泛用于耐火材料， 冶金添加劑。

Black silicon Carbide Black silicon Carbide is produceesd at high temperature in an electric resistancetype furnace with puarts sand and petoleum coke as its main raw materials.Its hardness is between fused aluina and synthetic diamond.mechanical intensity of it is higher than fused alumina.It is brittle and sharp and has electrical and heat conductivity in some degree.The abrasives made of it are suitable for working on cast iron ,nonferrous metal,rock,leather,rubber,etc.It is also broadly used as refractory material and metallurgical additive.
