Compositions of the form, 80%(Ag1-xCuxI)-20%(2Ag2O•P2O5), where x ranged from 0.05 to 0.25, were prepared by quenching molten mixtures. They were then characterized by using X-ray diffraction, differential scanning calorimetry, complex impedance and transport number techniques. The X-ray diffraction data revealed the presence of glassy phases which were mixed with AgI or other polycrystalline phases. Complex impedance and transport number data for frequencies ranging from 65.5kHz to 1Hz suggested that the most conductive composition (x = 0.1) had a Ag-ion conductivity of 0.00864S/cm at room temperature.
