Synthesis of SiC nanofibers by annealing carbon nanotubes covered with Si

SiC nanofibers were synthesized using carbon nanotubes as templates by depo siting silicon on the templates of carbon nanotubers and then annealing the as-deposited specimen at 1200 degreesC for 15 min with a de self-heating m ethod. The analyses of X-ray diffraction (XRD), X-ray photoelectron spectro scopy (XPS), Raman scattering and scanning electron microscopy (SEM) were p erformed for the as-annealed specimen. The measurement results show that th e SiC phase (SiC nanofibers) and the graphite phase (carbon nanotubers) coe xist in the specimen, so the coaxial structure of the SiC nanofibers and th e carbon nanotubes is considered to exist.
