Fast ion conducting solid electrolytes are becoming increasingly important owing to their application in solid state ionic devices. The present work deals with the silver ion conducting x AgI – (1– x )Ag 2 Cr 2 O 7 electrolyte system. These electrolytes have been characterised by X‐ray diffraction, electrical conductivity, electronic conductivity and thermoelectric power techniques. A high ionic conductivity of the order of 10 −3 S/cm has been observed for the composition mol% 80 AgI–20 Ag 2 Cr 2 O 7 , at room temperature. The electronic conductivity of this electrolyte is three orders of magnitude lower than the ionic conductivity.
