Selected area electron diffraction (SAED) patterns along the main pseudo-cubic axes, which show a splitting of reflections, are calculated for tetragonal and rhombohedral distortions present around the morphotropic phase boundary of PbZr1-xTixO3 (PZT). If a defined splitting is observed it might be used to estimate the lattice distortion, although for a detailed analysis, especially to distinguish the monoclinic phase, convergent-beam electron diffraction is required.
