Abstract A method for synthesizing silicon carbide whiskers by microwave heating is described in this paper. Silicon carbide whiskers with diameter in the range of nanometer have been obtaind by the reduction of SiO2 with C in an atmosphere of nitrogen. Ultrafine SiO2 powder, phenol formaldehyde resin and carbon black are used as starting materials. The structures of the whiskers are determined by means of XRD, TEM. The effects of temperature and carbon type on the production of SiC whiskers are discussed.
