The glass-forming region in the AgI-Ag2O-V2O5 ternary system was determined. On the basis of this glass-forming region, the glass transition temperature, density, ionic conductivity and Raman scattering were determined for nAgI–3Ag2O–2V2O5 (n = 0 to 10) glasses. The glass transition temperature and the density varied linearly with AgI concentration. However, the activation energy for ionic conductivity and the electrical modulus indicated a different compositional dependence at about 40mol%AgI. It was shown that the network structure was essentially the same, both below and above this composition, by means of Raman scattering. The formation of a AgI partial structure in higher AgI-doped glasses, and its relationship to the cluster model, was explained in terms of the present experimental results and previous diffraction data.
