Abstract

To determine the phase boundary between diaspore ( α – AlOOH) and δ – AlOOH, in situ X – ray di ﬀ raction experiments were carried out using a multi – anvil high – pressure apparatus and synchrotron X – ray. The stability of each phase was determined by observing the change in powder X – ray di ﬀ raction patterns. The equilibrium phase boundary is described by the formula P (GPa) = 12.2 (±4.9) + 0.0027 (±0.0044) × T (K). The boundary determined in this study is located at a lower pressure than that estimated by previous quenching experimental studies.

一水硬铝石与δ-AlOOH相界的原位x射线衍射研究

为了确定一水硬铝石(α - AlOOH)和δ - AlOOH之间的相界，采用多砧高压仪器和同步加速器X射线进行了原位X射线衍射实验。通过观察粉末X射线衍射图的变化来确定各相的稳定性。平衡相边界由公式P (GPa) = 12.2(±4.9)+ 0.0027(±0.0044)× T (K)描述。本研究确定的平衡相边界位于较低的压力下。

期刊介绍： The Journal of Mineralogical and Petrological Sciences (JMPS) publishes original articles, reviews and letters in the fields of mineralogy, petrology, economic geology, geochemistry, planetary materials science, and related scientific fields. As an international journal, we aim to provide worldwide diffusion for the results of research in Japan, as well as to serve as a medium with high impact factor for the global scientific communication Given the remarkable rate at which publications have been expanding to include several fields, including planetary and earth sciences, materials science, and instrumental analysis technology, the journal aims to encourage and develop a variety of such new interdisciplinary scientific fields, to encourage the wide scope of such new fields to bloom in the future, and to contribute to the rapidly growing international scientific community. To cope with this emerging scientific environment, in April 2000 the journal''s two parent societies, MSJ* (The Mineralogical Society of Japan) and JAMPEG* (The Japanese Association of Mineralogists, Petrologists and Economic Geologists), combined their respective journals (the Mineralogical Journal and the Journal of Mineralogy, Petrology and Economic Geology). The result of this merger was the Journal of Mineralogical and Petrological Sciences, which has a greatly expanded and enriched scope compared to its predecessors.
