摘要：

The bulk samples of nanophase PbF2(n-PbF2) with the clean interfaces were prepared by using an inert gas evaporation and in situ compacting technique. The phase constitution and ionic conductivity were studied by XRD, DSC and complex impedance spectra. The results show that the ionic conductivity of n-PbF2 is rather higher than that of coarse-grained PbF2. The temperature of phase transition from alpha-phase to beta-phase for n-PbF2 drops about 30 degrees C compared with that of coarse-grained PbF2.
