Abstract
The minimum in the d. c. and a. c. conductivities, dielectric constant, glass transition temperature and density observed in the glasses 50V2O5(50-x)P2O5-xMO with MO=Bi2O3 or Sb2O3 at x≃25-30 mol% of MO is found to be due to the lowest value of the ratio of V5+/V4+ appearing at the same concentration could, however, be well fitted with the Mott's polaron theory. The glass forming oxides also affect the activation energy for hopping conduction.
