Abstract

We have carried out single crystal X-ray diffraction measurements of (Bi2O3)0.75(Gd2O3)0.25 in the temperature range between 123 and 292 K. The structure was refined by the least-squares method, using about 70 reflections. The structure is very similar to that of δ-Bi2O3 and it was concluded that the oxygen ions are statistically located towards the cations ascribing to relatively short GdO bond distance. The decrease of the ionic conductivity is mainly due to the difference between electronegativities of BiO and GdO bonding.
