摘要

高分辨率中子衍射对重要压电材料锆钛酸铅(PZT)进行了研究，发现氧无序在立方相中存在。这一意想不到的结果表明，在这一相中，在室温铁电相中仍然存在倾斜氧八面体的残余。结果是，立方相，远不是一个简单的晶体结构，表现出比迄今为止认为的更复杂的局部结构。

The not so simple cubic structure of PbZr(1-x)Ti(x)O3 (PZT): complex local structural effects in perovskites.

High-resolution neutron diffraction on the important piezoelectric lead zirconate titanate (PZT) has found that oxygen disorder exists well into the cubic phase. This unexpected result shows that within this phase there persists a remnant of the tilted oxygen octahedra present within the room-temperature ferroelectric phase. The result is that the cubic phase, far from having a simple crystal structure, exhibits a more complex local structure than had hitherto been thought.

期刊介绍： Acta Crystallographica Section B: Structural Science, Crystal Engineering and Materials publishes scientific articles related to the structural science of compounds and materials in the widest sense. Knowledge of the arrangements of atoms, including their temporal variations and dependencies on temperature and pressure, is often the key to understanding physical and chemical phenomena and is crucial for the design of new materials and supramolecular devices. Acta Crystallographica B is the forum for the publication of such contributions. Scientific developments based on experimental studies as well as those based on theoretical approaches, including crystal-structure prediction, structure-property relations and the use of databases of crystal structures, are published.
