Abstract

The glass formation region and the electrical conductivities of glasses in the PbF₂ MnF₂ Pb(PO₃)₂ system are reported. A glass with composition 45PbF₂-45MnF₂10Pb(PO₃)₂ shows maximum anion conductivity ≈ 4 × 10^-4 (Ω-cm)^-1 at 200°C. Conductivity maxima observed, with composition variation, for these glasses have been explained by a displacement mechanism between Mn²⁺ and Pb²⁺ which in turn promotes fluoride anion mobility. Electrical relaxation characteristics have been studied by modulas spectroscopy and the departure from exponential relaxation has been correlated with the activation energy for conductivity.
