The per（ormanees of oxygen content, temperature and pressure on the oxidation behavior of HfC were thermodynamically investigated. The results of equilibrium thermodynamic calculations reveal that the amount of O2 affects the types and amounts of residual （2-0 products; the temperature has a significant influence on the solid phase structures of HI and C products; and the effect of total pressure results in the production of different types and amounts of C-containing gases. It is concluded that the temperature and O2 content are the major fa...
