Abstract

Superionic conducting glasses in the system 60Agl-20Ag2O-20[xB2O3-(1−x)WO3] were prepared by heating the appropriate amounts of the materials in an open quartz crucible at 650 ° C and quenching the melt in liquid nitrogen. The electrical conductivity of these samples was measured at 1 kHz on pressed pellets with electrodes made up of silver powder and this electrolyte. The mixed former effect has been observed in the present system, where the conductivity of the compositions studied was greater than the individual ternary systems. The electronic contribution to the total conductivity was determined using Wagner's polarization technique. The electronic conductivity was around six orders of magnitude less than the total conductivity. The transport number was almost equal to unity.
