Conductivity was characterized for the MI -AgI family (where M = NH4), which results when NH4 + is exchanged for Ag + in the binary system xAgI-(1-x)NH4I as a study model with concentrations of x = 0.4, 0.5, 0.6, 0.7.0.8 and 0.9. The study samples were grown using the slow evaporation method, and their properties were identified by Impedance Spectroscopy techniques. For this system in each of the concentrations, there was a decrease in the temperature at which the transition from poorly
