【摘要】 本文对ＳｉＣ颗粒、晶须和纤维的制备方法和碳热还原反应作了探讨，碳熟还原应作了制备ＳｉＣ材料的主要反应可为两个基本过程，首先为ＳｉＯ气的产生，其次ＳｉＯ直接与Ｃ反应生成ＳｉＣ，或ＳｉＯ成硅再与Ｃ反应生成ＳｉＣ。更多还原

【Abstract】 This paper aims to review the current synthesis methods of SiC particles ,whiskers and fibers. The carbothermal reduction of SiO 2 can be divided two steps. The first step is the generation of SiO gas. The second step is that SiO reacts with Carbon to produce SiC, or SiO are decomposed to Si And O 2, then Si reacts with C to produce SiC.更多还原
