Comparison of superionic phases for some fluorine conducting materials
AbstractImpedance spectroscopy data for a several materials with high ionic conductivity in the temperature range 298–473 K were obtained and analyzed. Investigated systems included pure PbSnF4, KSn2F5, RbSn2F5 and solid solutions based on PbSnF4 and SnF2. The values of the dc conductivity and activation energies are estimated from the analysis of the conductivity spectra. The factors which influence on conductivity, phase transitions and activation energies in the given system have been established
