Abstract:

SiC nanometer whisker, whose diameter was about 50nm and purity was 98.54%, was synthesized by microwave heating in an atmosphere of argon. Char pyrolyzed phenolformaldehyde resin and SiO2 nanometer powder were used as starting materials. The properties of the whisker were determined by XRD and TEM. The mechanism for synthesizing SiC nanometer whisker was discussed.

Key words: SiC, Nanometer whisker, Char, Microwave synthesis
