It was shown that small concentrations of Pb, Cl or S (table 246) did not affect the activation energy for electrical conduction and hardly changed the phase transition temperature. It was suggested that the dopants, which formed solid solutions with the host, produced little change in the stability and conductivity of the electrolyte at room temperature, within the solid solution range.
