Recovering the magnetocaloric properties of La0.8Ce0.2Fe11.5Mn0.2Si1.3Hy by secondary solid-state hydrogenation
Source abstract
Abstract
The hydrogenation of La 0.8Ce 0.2Fe 11.5Mn 0.2Si 1.3 alloy was realized by post-annealing the mixture of it with metallic hydride Sm 5Mg 41H x. During the annealing, the released hydrogen from the metallic hydride was absorbed to form La 0.8Ce 0.2Fe 11.5Mn 0.2Si 1.3H y. Interestingly, it was found that the secondary solid hydrogenation could further release the hydrogen from the residual metallic hydride to recover the dehydrogenated La 0.8Ce 0.2Fe 11.5Mn 0.2Si 1.3H y. This work proposes a facile way of obtaining the La(Fe, Si) 13H y-type hydrides through a solid-state hydrogenation, which exhibits a merit of recovering possibility in case the dehydrogenation of La(Fe, Si) 13H y-type hydrides occurs under the service.
