摘要

本研究调查了先前从四种抗硫酸盐硅酸盐水泥熟料中分离出的褐磨矿的两个晶体位置之间铁的定量分布。57Fe Mössbauer光谱与粉末x射线衍射（XRD）相结合，确定了正交结构中四面体和八面体位置上Fe3+和Al3+离子的平衡。研究了覆盖整个组成范围的合成样品以进行方案验证。

Mössbauer study of synthetic and extracted brownmillerite from sulfate resisting Portland cements'

This study investigates the quantitative distribution of iron between the two crystallographic sites of brownmillerite isolated in a previous study from four sulfate resisting (SR) Portland cement clinkers. ⁵⁷Fe Mössbauer spectroscopy was combined with powder x-ray diffraction (XRD) in order to determine the balance between Fe³⁺ and Al³⁺ ions in the tetrahedral and octahedral sites of the orthorhombic structure. Synthetic samples covering the whole composition range were studied for protocol validation.

期刊介绍： The Journal of the American Ceramic Society contains records of original research that provide insight into or describe the science of ceramic and glass materials and composites based on ceramics and glasses. These papers include reports on discovery, characterization, and analysis of new inorganic, non-metallic materials; synthesis methods; phase relationships; processing approaches; microstructure-property relationships; and functionalities. Of great interest are works that support understanding founded on fundamental principles using experimental, theoretical, or computational methods or combinations of those approaches. All the published papers must be of enduring value and relevant to the science of ceramics and glasses or composites based on those materials. Papers on fundamental ceramic and glass science are welcome including those in the following areas: Enabling materials for grand challenges[...] Materials design, selection, synthesis and processing methods[...] Characterization of compositions, structures, defects, and properties along with new methods [...] Mechanisms, Theory, Modeling, and Simulation[...] JACerS accepts submissions of full-length Articles reporting original research, in-depth Feature Articles, Reviews of the state-of-the-art with compelling analysis, and Rapid Communications which are short papers with sufficient novelty or impact to justify swift publication.
