Nanoparticles and nanorods of SiC were synthesized using arc-plasma processing of coarse particles. X-ray diffraction and Raman spectroscopic studies showed the presence of β-SiC and carbon nanotubes in the starting coarse particles and SiC nanorods in the ultrafine particles produced by plasma processing. Scanning electron microscopy and transmission electron microscopy confirmed the presence of carbon nanotubes in the starting material and nanorods of SiC in the plasma-processed samples.
