Abstract: Samples of general formula 4AgI‐(1‐x)PbI2‐2xCuI, x = 0–0.4, have been prepared and investigated by XRD, DSC, and temperature‐dependent conductivity studies. X‐ray diffractograms showed the presence of binary system consisting of AgI and PbI2 in the sample x = 0. Cu‐substituted samples showed very similar diffractograms to that of the pure compound which indicates that no effect for the substitution on the nature of the binary system. DSC curves showed the presence of phase transition whose temperature increased with Cu+ ratio in the system. Ionic conductivity measurements confirmed the occurrence of the phase transition and showed that the high temperature phase is superionic conducting, whose conductivity increases with the increasing Cu+ amount in the system.
