  • Abstract

    An experimental attempt was made to analyze structural and ion transport properties in the case of a new mixed system viz., (BiI3)v - (Ag2WO4)100-v where y = 10, 20, 30, 40, 50, 60, 70, 80 and 90 mol% respectively. The samples synthesized by the rapid melt-quenching technique were analyzed using Fourier Transform Infrared (FT–IR) spectroscopy, differential scanning calorimetric (DSC) analysis and silver ionic transport number studies. The results of FT–IR and DSC studies have revealed the formation of AgI and other phases in various compositions of the system. The transport number measurements carried out by Wagner’s and EMF methods have indicated that silver ions may be responsible for the observed ionic transport in these newly formed solid electrolyte phases.
