Preparation and characterization of fast ionic solids in new ternary system CuI–Ag2O–PbO2

An experimental attempt was made to characterize a variety of compositions in a ternary system (CuI)x–(Ag2O–PbO2)100−x where x=25, 30, 35, 40, 45, 50, 55, 60, 65 and 70 mol%. The samples were analysed using X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, differential thermal analysis (DTA) and silver ionic transport number studies. The results of XRD, FTIR and DTA studies have revealed the formation of AgI and other phases in the various compositions of the system. The transport number measurements carried out by Wagnerʹs and EMF methods have also indicated that silver ions are the majority charge carriers in these compositions.
