The symmetry of single-crystal piezoelectric PbZr1-xTixO3, with x approximate to 0.31 and x approximate to 0.46, has been investigated by high-resolution x-ray diffraction, both at room temperature and up to and above the Curie temperature. Reciprocal space maps around a selection of Bragg reflections were collected and self-consistent patterns showing Bragg splittings were observed. The analysis of the separation of peaks from different twin domains provides precise information on PbZr1-xTixO3 symmetry when approaching the morphotropic phase boundary at x = 0.48 from the zirconium-rich side.
