Structural Aspects and Thermal Properties of the Solid Fast Ionic Conductor [xCuI:(1-x)Ag2CdI4] (x = 0.2, 0.4, 0.6 and 0.8 mol. Wt %)

The [xCuI:(1-x)Ag2CdI4] fast ionic conductors with various compositions corresponding to x=0.2, 0.4, 0.6 and 0.8 mol. wt % have been prepared by solid state reaction. The fast ionic conductors are characterized by X-ray powder diffraction, FTIR, DTA, DSC, TGA studies. The transmittance spectra of the fast ionic conductors [xCuI:(1-x)Ag2CdI4] (x=0.2, 0.4, 0.6 and 0.8 mol. wt. %) have been measured in the mid-infrared range to investigate the structure of the cadmium iodate anion [(CdI4)2-] matrix and the nature of sites hosting the charge carrier copper ions. X-ray powder diffraction, DTA, DSC, TGA studies was also carried out for confirming doping effect in the formation of composite in which the interface layer plays an important role in controlling the bulk properties of the material
