Abstract

Large-scale silicon carbide nanowires were prepared by using pure silicon powder and phenolic resin, which were mixed, molded, carbonizated, and then subjected to the microwave heating with a rate of 10℃/min between 1300℃ and 1400℃ in the static argon atmosphere for 0.5--2h. The SiC nanowires were characterized by means of SEM and TEM, the composition of samples were determined through EDX. The prepared nanowires show a core-shell structure with diameters ranging from 20nm to 100 nm. The results show that liquid silicon acts as catalyst and key raw material for preparing SiC nanowires.

Key words： silicon carbide; nanowire; phenol formaldehyde resin; microwave heating
