摘　　要：用自制的树脂热解炭和ＳｉＯ２纳米微粉作原料，用微波加热的方式合成了粒径在１５ｎｍ左右、纯度达９８６ｗｔ％的超细ＳｉＣ纳米微粉。用化学成分分析法、Ｘ射线衍射法、Ｘ射线小角散射法、透射电子显微镜等分析测试手段对得到的ＳｉＣ纳米微粉进行了表征，研究并分析了其合成机理。Ultrafine SiC nanometer powder, whose diameter was about 15nm and purity was 986%, was synthesized by microwave heating in an atmosphere of argon. Char pyrolyzed from phenolformaldehyde resin and SiO2 nanometer powder were used as starting materials. The properties of the powder were determined by XRD, TEM and so on. The mechanism for synthesizing ultrafine SiC nanometer was discussed.
