Abstract: As one of the most promising ionic conducting system for application, PbCl2-PbOwas studied on the modification with doping potassium chloride.It was found that a little amount of KC1 could make the sample be directly sintered in air.The samples with nominal composition of [(PbCl2)0.55 (PbO)0.45](1-x)(KCl)x(z=0-0.30) were measured by ACcomplex impedance technique, Wagner DCpolarization and potentiometric methods.X-ray diagram indicated the main phase in the highly conducting system.For the samples within the composition range of 0.05<x<0.22, the lowest value of conductivity was observed, and the role of mixed grain boundaries was used to account for this phenomenon.
