Structural, Thermal and Electrical Properties of Ionic Conductors (AgPO3)1-x(Ag2SO4)x Glass Systems

Abstract

This study aims to investigate the effect of temperature and frequency on the ac conductivity of ion conducting glasses systems of (AgPO3)1-x(Ag2SO4)x, where x = 0.00, 0.10, 0.15, 0.20 and 0.25. Structural characterisation was examined in different samples using different techniques. At lower frequency range, the frequency dependence of the total conductivity was nearly constant and then followed a power relation as frequency and temperature increased. The observed values of the exponent S were somehow frequency-dependent and decreased with increasing temperature from 1.3 to 0.2 for the composition when x = 0.15. The cutoff frequency from dc to the dispersive region, ωc, increased with temperature. In addition, ωc values were within the same range as other values. Total conductivity σtot(ω) was found to be thermally activated of the Arrhenius type.
