Description
Methods of thermodynamic, kinetic and X-ray phase, thermal and mass-spectrometric analysis are used to study the main regularities of phase formation in MC1-x+MmOn (M=Ti, Zr, V, Nb) reaction mixtures in the temperature range up to 1870 K. It is stated that interaction in the given systems is characterized by consecutive reduction of higher oxide (excluding ZrO2) up to M2O3 (M=Ti, V) or MO2 (M=Nb), subsequent formation of oxycarbide phases by MC1-x+M2O3(MO2) → MOzCy + CO chemical reaction, dissolution of the formed oxycarbide in initial isostructural carbide. In M5C1-x + Mm5On mixtures the process is completed by formation of M2C(O) hexagonal oxycarbide or a metal
