Raman spectroscopy characterization of uranium hydride and deuteride

Initial decomposition mechanisms and the inverse effects of temperature and PH2 on the thermodynamic stability of UH3

“…1 Since this hydriding reaction is reversible and UH 3 can decompose to metal U and H 2 upon heating, 1 U has been also used as the storage medium for hydrogen and especially its isotopes (deuterium and tritium) in handling facilities. 1–6 Therefore, investigations of the decomposition mechanism and thermodynamic stability of uranium hydride are critical to industrial applications of hydrogen isotope separation 6 and scientific studies on corrosion science of U. 7…”

[1][2][3][4][5][6] Therefore, investigations of the decomposition mechanism and thermodynamic stability of uranium hydride are critical to industrial applications of hydrogen isotope separation 6 and scientific studies on corrosion science of U. 7 The thermal decomposition properties of UH 3 , namely, UH 3 dehydrogenates and releases H 2 molecules into the environment under certain temperature (T) and hydrogen pressure (P H 2 ) conditions (P H 2 -C-T), have been explored by early experiments, especially the well-known relationship between P H 2 of the plateau region and T (van't Hoff curve).…”
