V2O5 Sol - Gel was prepared from industrial V2O5 crystal sheet by the inorganic sol - gelmethod. Viscosity variation of V2O5 sols was studied. The thermal analysis of V2O5 gels and V2O5 crys-tals was taken. The research result indicated that suitable technological parameters for preparation ofV2O5 sol - gel are: melting temperature of V2O5 crystal being 800~900℃, holding time of meltingtemperature being 5 ~ 10 min. The so1 can form gel when the concentration of sols is higher than 22 g/L. The viscosity of sol will increase as prolonging the placed - time, and the viscosity increases morewhen the concentration is higher. The component of V2O5 gels keeps stabilization in heating conditions(below 500℃), and phase transformation does not occur.
