Transport property and structural characterization studies on (1 - x)(0.75AgI:0.25AgCl):xTiO2 conducting composite electrolyte system
Transport property and structural investigation have been carried out on newly synthesized Ag+ ion conducting composite electrolyte system. The composite electrolyte system (1 - x)(0.75AgI:0.25AgCl):xTiO2, where 0 (less-than or slanted equal to) x (less-than or slanted equal to) 0.5 (in molar weight fraction) has been synthesized by melt quenching and annealing methods. The chemical compound TiO2 (second phase dispersoid) dispersed in different compositions in a quenched (0.75AgI:0.25AgCl) mixed system/solid solution; this solid solution was used as a first phase host salt in place of AgI. The different preparation routes were adopted for the composite electrolyte system. Composition x = 0.1 exhibited highest conductivity at room temperature. The composite system 0.9(0.75AgI:0.25AgCl):0.1TiO2 was synthesized at different soaking times by melt quenching method. The system exhibited optimum conductivity at 20 min soaking time ( sigmart approximately = 1.4 x 10-3 S/cm). The ac conductivity has been measured from Z'-Z'' (Cole-Cole) complex impedance plots using impedance spectroscopic (IS) technique. The electrical conductivity as a function of temperature and frequency has been studied, and activation energy Ea, was calculated from Arrhenius plots for all compositions (0 (less-than or slanted equal to ) x (less-than or slanted equal to) 0.5). The dc conductivity value has been evaluated from Log sigma vs. log f plots. Structural characterization studies were carried out by X-ray diffraction (XRD) and differential thermal analysis (DSC) techniques.
