The commercial SiO powder and the arc-discharge plasma pretreated carbon black were mixed and used as the source materials. The heating-up and reaction time is less than half an hour. It was found that most of the nanowires have core-shell SiC SiO2 nanostructures. The nucleation precipitation and growth processes were discussed in terms of the oxide-assisted cluster-solid mechanism. Keywords Silicon carbide Nanowires Induction heating Introduction Silicon carbide SiC has been widely used in the fields of electronic and optic devices due to its unique properties such as a wide band gap of eV high strength and Young s modulus good resistance to oxidation and corrosion excellent thermal conductivity and electron mobility 1-4 .
