摘　　要：用自制的酚醛树脂热解炭作炭源，用ＳｉＯ２超细粉作硅源，根据碳热还原原理，利用常规加热和微波加热两种方式，分别制备了直径在纳米级的ＳｉＣ晶须。Ｘ射线衍射、透射电镜检测结果表明：制备工艺和条件对ＳｉＣ晶须的性质有较大的影响。Silicon carbide whiskers, diameter of which is in the range of nanometer, are prepared by conventional heating and microwave heating in nitrogen atmosphere. Ultrafine SiO 2 powder, phenol(formaldehyde) resin are used as starting materials. The properties of the whiskers are determined by means of XRD, TEM, and so on. The results show that technique and condition for preparing samples have obvious effect on the whiskers characteristics.
