SiC powder was heated in air over the temperature range of 1100-1350℃.The β-cristobalite was formed on the surfaces of SiC particles by the reaction:
SiC(s) + 2O₂(g) = SiO₂(s) + Co₂(g)
It is assumed that the diffusion od oxygen ion through the formed surface layer of β-cristobalite controled oxidation of the SiC particles.
The diffusion coefficient of oxygen ion through the β-cristobalite layer was obtained as the following equation:
D=3.84 × ?? exp (-14.7/RT)
