Abstract
The stoichiometry and/or crystal structure of vanadium oxide particles are altered by heating initial particles of vanadium oxide under mild conditions. The temperature is generally at least about 300.degree. C. less than the melting point of both the initial vanadium oxide particle and the product vanadium oxide particles. Preferred initial particles are vanadium oxide nanoparticles. The heating can be performed under an oxidizing atmosphere or an inert atmosphere, depending on the particular initial particles and the desired product particles.
