摘要
这项研究对钌的高压和高温相图进行了现场表征。该实验在欧洲同步辐射设施(ESRF)的 ID27 光束线结合使用了激光加热金刚石砧室(LH-DAC)和 X 射线衍射(XRD)技术。在 15 GPa 到 110 GPa 的范围内以及从环境温度到 6600 K 的温度范围内收集了 XRD 图样。虽然没有观察到预测会在高温下发生的 hcp-fcc 转变,但这项研究首次在实验中观察到了 Ru 在高温条件下的固液相变。报告中的 P-V-T 状态方程在 100 GPa 和 3000 K 下均有效。
Phase diagram of ruthenium characterized In Situ by synchrotron X-ray diffraction and Ab Initio simulations
In this work, an in situ characterization of the high-pressure and high-temperature phase diagram of ruthenium was carried out. This experiment was performed using a combination of laser-heated diamond anvil cell (LH-DAC) and X-ray diffraction (XRD) techniques at the beamline ID27 of the European Synchrotron Radiation Facility (ESRF). XRD patterns were collected in the range of 15 GPa to 110 GPa and from ambient temperature up to 6600 K. While the hcp-fcc transition, predicted to occur at elevated temperatures was not observed, this study has produced the first experimental observation of a solid–liquid phase transition of Ru at HP conditions. A P-V-T equation of state valid up to 100 GPa and 3000 K is reported.

期刊介绍:
Results in Physics is an open access journal offering authors the opportunity to publish in all fundamental and interdisciplinary areas of physics, materials science, and applied physics. Papers of a theoretical, computational, and experimental nature are all welcome. Results in Physics accepts papers that are scientifically sound, technically correct and provide valuable new knowledge to the physics community. Topics such as three-dimensional flow and magnetohydrodynamics are not within the scope of Results in Physics.
Results in Physics welcomes three types of papers:
1. Full research papers
2. Microarticles: very short papers, no longer than two pages. They may consist of a single, but well-described piece of information, such as:
- Data and/or a plot plus a description
- Description of a new method or instrumentation
- Negative results
- Concept or design study
3. Letters to the Editor: Letters discussing a recent article published in Results in Physics are welcome. These are objective, constructive, or educational critiques of papers published in Results in Physics. Accepted letters will be sent to the author of the original paper for a response. Each letter and response is published together. Letters should be received within 8 weeks of the article''s publication. They should not exceed 750 words of text and 10 references.
