Structural phase transitions in the x(AgI+KI)+(1-x)NH4I system, allowed quantifying the structural relaxation of the phases: : NH4Ag4I5 and : KAg4I5 respectively, being correlated with the NH4I content and with the presence of the glass phase within the compound. It is noticed the importance of having a first thermal treatment of the compound, in order to erase the thermal history. The spontaneous liberation of the residual enthalpy is achieved by using a Ta = 308 K isotherm for a twohour time span. Based on the obtained data, it is presented the phase diagram for variations from x = 0.45 to 0.95.
