With the use of microscopic, spectroscopic, gravimetric and diffraction methods the kinetics and 
peculiarities of spontaneous and thermally-induced polycondensation of molybdenum and 
vanadium oxoacids in aqueous medium has been investigated. It has been shown that 
polycondensation occurs with the induction period the length of which exhibits an increase at the 
rise of V : Mo ratio. The polycondensation rate and the length of the induction period is very 
sensitive to the presence of surfactants and polymers in the mature solution that permits one to 
exert an effective control over the process of the colloidal oxide formation.  The mechanism of 
polycondensation processes during solvathermal synthesis of bare and mixed oxides of 
molybdenum and vanadium of general composition (1-x)V2O5 : xMoO3 was proposed.
