Abstract

Samples of binary silver phosphate glasses with composition (Ag ₂O)_x(P₂O₅)_1-x have been prepared and their AC electrical conductivities measured over a range of frequency, composition and temperature. It is observed that AC conductivity increases very gradually at low frequency (below 1 kHz), but rapidly at higher frequency (above 10 kHz). Conductivity as high as 10^-5 Scm^-1 has been observed depending on the composition, frequency and temperature of the samples. The conductivity increases almost linearly with the mole fraction of Ag₂O, and also increases with temperature. The Arrhenius plot is obeyed and an activation energy of 0.41 to 0.46 eV has been obtained
