Abstract

Recently we have reported the existence of fast ionic conduction in silver halide-rich all-halide glasses. In the present paper we report glass formation from x = 0.08-1.0 in a pseudobinary halide-pyrophosphate system x(AgCl)0.64(CsI)0.36 + (1-x)(Ag2PO3.5) and study the composition dependence of the conductivity. Glass transition temperatures and activation energies for d.c. conductivity increases smoothly as the pyrophosphate concentration increases, while the conductivity correspondingly decreases. The frequency dependence of the conduction process has been analysed. The conductivity relaxation process becomes increasingly non-exponential as the conductivity at some fixed temperature (eg. 298 K) increases.
