【摘要】 用X射线光电子能谱(XPS)分析研究了金属铀表层和八氧化三铀的表面结构以及一氧化碳对其表面结构的影响。在一氧化碳气氛中金属铀表层氧化物和八氧化三铀中氧含量减少,O/U比值分别下降了7.2％和8.0％。研究结果表明,一氧化碳气氛可抑制金属铀表面及其氧化物的进一步氧化。更多还原

【Abstract】 The surface structures of uranium metal and triuranium octaoxide (U3O8) and the influence of carbon monoxide to the surface layers have been studied by X-ray photoelectron spectroscopy (XPS). After exposure to carbon monoxide, contents of oxygen in the surface oxides of uranium metal and U3O8 are decreased and O/U ratios decrease 7. 2% ,8.0% respectively. The investigation indicated the surface layers of uranium metal and its oxides were forbidden to further oxidation in the atmo-sphere of carbon monoxide.更多还原
