摘要：

The structure refinement from x-ray diffraction data of PbZrO3 single crystals revealed that the parameters of the mean thermal displacements for Pb ions in the high-temperature paraelectric phase (SG Pm3m) showed unrealistically large values. Therefore models with displacements of Pb ions in several relevant directions were tested. A shift in the [100] direction yielded both the lowest R-value and the most sensible mean thermal displacement.
