【 摘 要 】

Thermodynamic analysis of higherature interactions in Ti-C-H-N, Ti-O-C-H-N systems was carried out, corresponding to the processes of titanium carbide synthesis in the conditions of plasma flow using various titanium-containing raw materials. Modeling processes in these carbide-forming systems showed that the formation of titanium carbide is possible in equilibrium and quasi-equilibrium conditions, at temperatures below 3500 K, with stoichiometric and excess carbon according to gas-phase reaction involving titanium and cyanide vapour. The possibility of achieving a high yield of titanium carbide in real synthesis conditions is predicted.
