A vanadium-oxide-based precursor fine powder was prepared by the reaction of vanadium metal and H2O2. A VO2 powder with particles tens of nanometers in size was obtained by treatment of the precursor powder at 650°C in an H2/Ar atmosphere. The particle size of the resulting VO2 powder was 40 nm, and the transition temperature of the obtained VO2 powder was 68.5°C.
