Change in electrical conductivity, radiation, and thermal stability of PbN6, coprecipitated with CuN6 and AgN3, are studied during radiolysis in vacuum. The data show a decrease in conductivity in proportion to addition of Cu2 ions and a slight decrease with addition of Ag ions. This is due to formation of a CuN6 intrusion in the PbN6 solid solution and decrease in concentration of mobile anion vacancies and, tentatively, formation of PbN6-AgN3 replacement solid solutions. Saturation with Ag ions occurs only at high concentrations, while radiolysis inhibition by Cu2 ions stops increasing at about 0.05 mole Cu2. Ag is an electron donor in the process and Cu2 is an acceptor.
