Abstract—The interaction of V₂O₅ and MoO₃ was studied by the contact annealing method both in the presence and
absence of the external electric field. The process occurs via the transfer of the components of both oxides and is
accompanied by the formation of new phases. The external electric field causes a sharp decrease in the reaction dif-
fusion flow of V₂O₅, and the rate of MoO₃ transfer changes depending on the polarity of the voltage applied.
