In the present report, an intensive evaluation of transport properties of superionic materials in a pseudoternary system (Cu1-xAgxI)-(Ag2O)-(CrO3), where 0.05 less than or equal to x less than or equal to 0.25, has been described. Room temperature conductivity studies have shown the formation of solid electrolytes with electrical conductivities of the order of 10 - 4 to 10 - 3 S cm - 1 at 295 K. The observed temperature-dependent electrical conductivity behavior is similar to. that of conventional solid electrolytes. Impedance and modulus analyses have indicated the temperature-independent distribution of relaxation times and the non-Debye behavior of these materials. The values of silver ionic transport number (t(Ag+)) obtained by EMF technique are nearly equal to the corresponding ionic transport number (t(i)) values estimated from the Wagner's polarization method, thus suggesting the formation of silver ion-conducting solid electrolytes in the chosen system. The present thermoelectric power (TEP) data are found to confirm the formation of silver ion-conducting glassy electrolytes in this system.
