Synthesis and Structural Transformation of [0.7(Ag2CdI4):0.3(AgIx:CuI(1-x))] of Fast-Ion Conductor (x = 0.2, 0.4, 0.6 and 0.8 Mol. Wt. %)

Some novel fast ionic solids in the mixed system were made to prepare [0.7(Ag2CdI4):0.3(AgIx:CuI(1-x))] where x = 0.2, 0.4, 0.6 and 0.8 mol. wt. % respectively by solid state reaction and quenching them at particular temperature. Powdered samples of different compositions containing x mol. wt. % of (AgIx:CuI(1-x)) were synthesized by solid state reactions, using [Ag2CdI4] ternary halides as host. Powder specimens of these compositions were analyzed using differential thermal analysis (DTA), differential scanning calorimetry (DSC), thermal gravimetric analysis (TGA), Fourier transmission infrared spectra (FTIR) and x-ray powder diffraction (XRD) techniques. In host system, Ag and Cu substitution appears to stabilize the high-temperature, hexagonal structure to temperature well in excess of 445 K, associated correspondingly with the melting of the (Ag+:Cu+) sublattice and with the storage of iodide/or cadmium sublattices.
