 Abstract
The SiO vapor that was generated from a mixture of Si and was reacted at for 2 h under vacuum with carbon nanofibers to produce SiC nanofibers having an average diameter of 100~200 nm. In order to understand the gas corrosion behavior, SiC nanofibers were exposed to air up to . SiC oxidized to amorphous , but its oxidation resistance was inferior unlike bulk SiC, because of high surface area of nanofibers. When SiC nanofibers were exposed to Ar-1% atmosphere, SiC oxidized to amorphous , without forming , owing to the thermodynamic stability of .
