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.
