Abstract: Ionic conductivity of the Ag2O-MoO3-V205 system has been studied over a wide range of frequency, temperature and composition. A narrower glass forming region has been found in comparison to the corresponding Ag2O-MoO3-P2O5 and Ag2O-B2O3-P2O5 systems. The highest conductivity at room temperature, σrt, = 3.21 × 10-6Ω-1 cm-1 (d.c.) with an activation energy, Eact, of 0.466 eV, was observed for the glass former's ratio of unity. Further, it reached a maximum value of 2.2 × 10-2Ω̈-1 cm-1 with Eact = 0.153 eV when the oxide-base glass was dissolved with Agl. D.c. conductivity, hopping rate and relaxation time in the present system have been found to be characterized by the same activation energy. © 1988 Chapman and Hall Ltd.
