摘要
本文回顾了自1960年至今非化学计量的w stite Fe1-zO的热力学性质和结构方面，以及它的修饰——所谓的伪相——作为偏离化学计量的z和平衡温度的函数。文中还详细描述了平衡相图的复杂性。在1185 K附近的iron/ w stite边界上指定了一阶跃迁W′;重新考察了与T(W) > 1185 K和W'j at T(W ') < 1185 K (i和j = 1,2,3)相关的转换。综述了基于点缺陷稳定性及其聚类特征的结构确定方法。此外，伪相是基于缺陷簇的转变或它们的分布模式(即，渗透或上层结构)，包括电子载流子的变化来检查的。
The complex nonstoichiometry of wüstite Fe1-zO: Review and comments
Thermodynamic properties and structural aspects of the nonstoichiometric wüstite Fe1-zO, and its modifications - the so-called pseudo-phases - as functions of departure z from stoichiometry and of equilibrium temperature are reviewed from 1960 to present. The complexity of the equilibrium phase diagram is described in some details. The first order transition W ⇆ W′ is specified on the iron/wüstite boundary near 1185 K. Transitions correlated to the modifications Wi at T(W) > 1185 K and W'j at T(W′) < 1185 K (i and j = 1,2,3) are re-examined. Structural determinations based on the characterization of point defects stabilization and of their clustering are reviewed. Additionally, the pseudo-phases are examined based on the transformation of defect clusters or of their mode of distribution (i.e., percolation or superstructure) with the inclusion of changes in electronic charge carriers.
期刊介绍：
Progress in Solid State Chemistry offers critical reviews and specialized articles written by leading experts in the field, providing a comprehensive view of solid-state chemistry. It addresses the challenge of dispersed literature by offering up-to-date assessments of research progress and recent developments. Emphasis is placed on the relationship between physical properties and structural chemistry, particularly imperfections like vacancies and dislocations. The reviews published in Progress in Solid State Chemistry emphasize critical evaluation of the field, along with indications of current problems and future directions. Papers are not intended to be bibliographic in nature but rather to inform a broad range of readers in an inherently multidisciplinary field by providing expert treatises oriented both towards specialists in different areas of the solid state and towards nonspecialists. The authorship is international, and the subject matter will be of interest to chemists, materials scientists, physicists, metallurgists, crystallographers, ceramists, and engineers interested in the solid state.
