最近在PbZrxTi 1 − xO 3（PZT）相图中发现了几个中间相，它们位于反铁电-铁电和准同型相边界附近。从这些阶段中的一些超晶格反射是清晰可见的适当的电子衍射图案，因此已被用来提供有关其对称性的进一步信息。在这里，结构扭曲引起的新的阶段进行了讨论和他们的域结构相比，四面体和菱面体PZT。相干结构参数来解释所观察到的相变序列。
Several intermediate phases have recently been identified in the PbZrxTi1−xO3 (PZT) phase diagram, located close to the antiferroelectric-ferroelectric and morphotropic phase boundaries. Superlattice reflections from some of these phases are clearly visible in the appropriate electron diffraction patterns and have therefore been used to provide further information concerning their symmetry. Here, the structural distortions giving rise to the new phases are discussed and their domain structures compared with those of tetragonal and rhombohedral PZT. Coherent structural arguments are presented to explain the observed phase transition sequences.
