Abstract

Dynamic behaviour of electrical conduction and polarization in silver borophosphate glasses has been studied over wide range of frequencies and temperatures. The dielectric spectrum showed a strong dispersion in C′(ω) with rise in temperature which distinguishes the conduction process from a pure steady state. The observed behaviour was found to be temperature activated with an activation energy of 0.39 eV. The data have been analysed in terms of admittance plots and a model has been proposed on the basis of this analysis.
