Abstract

Seeking possible divalent cation conducting glasses, we have investigated glass formation and conductivity in Pb(PO₃)₂ + PbX₂ (X = halide) glasses. Glass formation is found to extend to 40 mol% PbF₂, 60 mol% PbCl₂, 80 mol% PbBr₂ but no glasses could be obtained with PbI₂. Comparison of PbBr₂- and PbCl₂-containing glasses suggests the observed conductivity is anionic. In this case it seems that 40 Pb(PO₃)₂·60 PbCl₂, with σ_200°C = 7.08 × 10^-6Ω^-1cm, may be the best anion-conducting glass yet reported. The PbBr₂-containing glasses have the lower activation energies, however, which would be consistent with cationic conduction. t₊ data are need to clarify.
