Abstract
The impedance spectra of CeF3/CeF3 bicrystal (two single crystals separated by a single intercrystalline boundary) between Ag-electrodes are studied over a 135 to 410 K temperature interval (including temperatures below room temperature). The bicrystal was prepared by thermal-diffusion welding under a pressure of 1.5 × 107 Pa at 1473 K in vacuum (∼10−2 Pa). It is shown that the intercrystalline boundary affects but insignificantly the bicrystal bulk impedance. The CeF3/CeF3 ionic conductivity is 3 × 10−6 S/cm at 293 K; it is mainly determined by transfer processes in the single crystal bulk.
