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 σ200°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.
