Abstract. Modelling the process to obtain vanadium dioxide in systems V – O – H – Na and V – O – H – S has been carried out using the program complex “Selector”. The latter is based on a computer method for thermodynamic analysis of equilibrium compositions. The dependences of the concentration of main components in V – O – H – Na and V – O – H – S systems on hydrogen index pH as well as the dependence of the VO 2 concentration on pressure in the system V – O – H – Na are given. The possibility to obtain vanadium dioxide in water solution of the systems involved has been estimated.

Keywords: vanadium dioxide, phase transition, thermodynamical equilibrium, concentration.
