Structure and Physical Properties of Solid and Liquid Vanadium Pentoxide

Abstract

The electrical resistivity of near-stoichiometric crystalline V2O5 has been measured as a function of crystal orientation and oxygen partial pressure from 25° to 300°C. Conductivity is insensitive to ambient atmosphere. The activation energy for conduction is 0.20 eV. Molten V2O5, however, is sensitive to oxygen partial pressure. Its conductivity is proportional to Po2−⅙. Anomalously high electrical resistivity was observed for glassy V2O5 films.
