Abstract: The technique of spectroscopy of impedances have be used to measure electric conductivity and in the range of temperature of 300 and 500 K. This technique it is used to study the nature of the processes of ionic conduction in solids. Using the system binary xAgI-(1-x)NH4I with concentrations of 0.6 and 0.8, like I model of study. A jump in the conductivity in the xAgI-(1-x)NH4I system with concentrations x = 0.6 and x = 0.8 for T = 406 K and T = 400 K, respectively which is reduced when exchanged NH4+ for Ag+ was observed AgI in the cooperative effects due to interaction of ion-ion and ion-network. The jump observed with the technique of impedance spectroscopy in this agglomerate is due to the presence of phases of AgI and corroborated with the technique of differential scanning calorimetry observed an absorption peak corresponding to phase α and β of AgI heat.
