Isotherms and crystallography of the hydrides of the system CaxEu1 12xNi5

The hydriding of the system CaxEu1 12xNi5 has been examined for various values of x using in-situ X-ray diffraction and pressure-composition measurement at 298 K. The single phase solutions which exist in this ternary intermetallic system for x = 0 to 0.25 and 0.8 to 1.0 exhibit hydriding behaviour closely related to that of the corresponding end member binary. Significant changes in the stability, ease of activation and the composition range of the hydrides of the ternaries compared to that of the \u201crelated\u201d binaries are observed.Peer reviewed: YesNRC publication: Ye
