Thermal image furnace melting and twin roller quenching were used to prepare the high fluoride conducting oxyfluoride glasses in the systems of ZnF2-PbF2-SiO2, BiF3-PbF2-SiO2 and MnF2-PbF2-SiO2. The dc electrical conductivities of these glasses were measured as a function of temperature. In all the systems, it was possible to find the glass compositions with high conductivitiy more than 10-4Scm-1 (200°C). The good correlation between logσ and the average polarizability calculated from the constituent cations was observed.
