Abstract

The phase domain of Ti₃O₅-Ti₂O ₃-Ti(CO) at 1580 K was determined from the formation energies of Ti(C_xO_y), as calculated via the Gibbs-Duhem equation. An extensive Ti(CO) domain is attributed to the high affinity between TiC and TiO. The phase domain of Ti₃O₅-Ti₂O ₃-Ti(CN) was obtained at 1673 K using the formation energies of Ti(C_xN_y). This study shows that the stable region for Ti₂O₃ is significantly small in the Ti₃O ₅-Ti₂O₃-Ti(CN) phase domain. It demonstrates the absence of TiO and Ti₂O₃ in the normal syntheses of TiC and Ti(CN) from TiO₂, respectively.
