【摘要】 以工业硅溶胶和碳黑为主要原料，用溶胶—凝胶和碳热还原法进行了合成ＳｉＣ晶须的试验，探讨了合成温度对产物组成微观形貌的影响。结果表明：合成ＳｉＣ晶须适合的温度为１６００℃，在此条件下得到的产物中ＳｉＣ 晶须含量最高（７４％以上）、质量最好。更多还原

【Abstract】 The experiment to prepare synthetic whisker SiC by sol - gel process and carbon thermal reduction method is done mainly with the application of the raw materials of industrial silica sol and carbon black . The influence of synthesizing temperature on the micro- appearance of the product’ s composition is discussed in this paper. The results show that the suitable temperature for the formation of whisker SiC is at 1600℃. The SiC content obtained in the product reaches more than 74% under this con dition and possesses the highest quality.更多还原
