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.
