Paper Title:
Characterization of High Temperature Oxidation Properties of Silicon Carbide Nanofibers
  Abstract

Carbon nanofibers were reacted with SiO vapor generated from a mixture of Si and SiO2 to produce silicon carbide nanofibers at 1350oC for 2 h under vacuum. The obtained SiC nanofibers with a diameter ranging 100~200 nm had the specific surface area as high as 124 m2/g. The SiC nanofibers were not oxidation resistant, showing nearly complete oxidation at 1000 oC after about 60 h in air, though the oxidation product was amorphous silica which was generally considered to be oxidation resistant. The poor oxidation resistance was attributed to the inherent nanoporous nature of the fibers resulted from the gas-solid reaction.
