Furthermore, Thermodynamics calculation of oxidation reaction of silicon carbide ceramic was investigated though HSC Chemistry 5.0 code based on Gibbs free energy.
The microscopy and structure of the obtained pyrolyzed product were characterized by field emission scanning electron microscopy(SEM) (S-4800, Hitachi), and the solid phases were measured by X-ray diffraction (XRD) (PANalytical X'Pert PRO).
The main oxidation reactions are predicted by thermodynamics calculation, and all the thermodynamics data could be found in HSC Chemistry 5.0 code.
Moreover, rough and porous structure appeared on the surface of the specimen obtained(Fig. 4) which might favor the impregnation of oxygen and the occurrence of subsequent oxidation.
When oxidized under 800°C, obvious crystal structure difference was discovered at 22.15°which was the characteristic diffraction spectra of SiO2 (JCPD01-082-1554).

The energy barriers and the reaction energies were evaluated with the accurate model chemistry method at G3(MP2) level after a non-dynamical electronic correlation detection.
Chemical vapor deposition (CVD) is one of the major techniques of fabricating SiC, yet the detailed gas-phase and surface chemistry of the SiC CVD are not clear.
