And Function

Rare earth metals are used as hydrogen isotope occluders and function as electrodes in neutron generator tubes. In this study, erbium dideuteride thin films have been quantitatively measured for purity in order to establish the deleterious effects resulting from film processing. These processes include deposition, hydriding, and neutron tube vacuum anneal. The data taken reveal that ∼0.02 mg/cm2 erbium metal is unavailable as the hydride due to surface oxidation and interfacial interactions between occluder metal and substrate.

REMgNi4-based alloys, RE(2−x)MgxNi4 (RE: rare-earth metals; 0 < x < 2), with a AuBe5-type crystal structure, exhibit reversible hydrogen absorption and desorption reactions, which are known as hydrogen storage properties. These reactions involve formation of three hydride phases. The hydride formation pressures and hydrogen storage capacities are related to the radii of the RE(2−x)MgxNi4, which in turn are dependent on the radii and compositional ratios of the RE and Mg atoms. The crystal structures formed during hydrogen absorption reactions are the key to understanding the hydrogen storage properties of RE(2−x)MgxNi4. Therefore, in this review, we provide an overview of the crystal structures in the hydrogen absorption reactions focusing on RE(2−x)MgxNi4.
