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, ω_c, increased with temperature. In addition, ω_c values were within the same range as other values. Total conductivity σ_tot(ω) was found to be thermally activated of the Arrhenius type.
