  ABSTRACT: A quaternary super-ionic glass system xAgI: (95-x) [Ag2O:2V2O5]: 5TeO2, where 40 ≤ x ≤ 65 in steps of 5, has been pre- pared by melt quenching technique. The prepared glass samples are characterized by X-ray, FTIR and DSC studies. As revealed by the FTIR spectra, the oxyanion network is not affected by the addition of AgI. The frequency dependence of the electrical conductivity for various glass compositions at different temperatures has been analyzed in terms of Jon- scher’s universal power law. The measurements reveal that the conductivity increases from σ = 7.62 × 10–7 S/cm to 1.15 × 10–4 S/cm with increasing AgI content. The temperature dependent conductivity obeys the Arrhenius relationship. The impedance and modulus studies indicate the non-debye type of the frequency dispersion for all the glass samples.
