Abstract

The solid-state reaction method was used to prepare (Ba_1-xPr_x)Ti_1-x/4O₃(x = 0.10-0.20) (BPT) ceramics. The solid solubility and site occupations of Pr ions in BPT were investigated using X-ray diffraction (XRD) and electron paramagnetic resonance (EPR) techniques. The results indicate that the solubility limit is x = 0.17, within which BPT ceramics exhibit a single-phase cubic perovskite structure. Pr ions are substituted predominantly for Ba-sites.

Key words： pr-doped BaTiO₃ X-ray diffraction electron paramagnetic resonance solid solubility site occupations
