Model of oxidation of SiC microparticles at high temperature

The oxidation kinetics of SiC microparticles has been studied from both experimental data and theoretical aspects based on recent research work. The effects of temperature, especially the particle size on the oxidation kinetics are explained not only qualitatively but also quantitatively based on our theory and model. The results show that our new model and the calculated results can reach a good agreement. It may also be seen that the important role of particle size in oxidation of SiC powder, especially in the nano era for SiC material.
