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
