Chemical hydrogenation of La(Fe,Si) family of intermetallic compounds

Abstract In the present work, the chemical hydrogenation process of La(Fe,Si) 13 compounds has been shown. It was found, that the La(Fe,Si) compound can be easily saturated with hydrogen by performing reaction with 0.6 M hydrochloric acid (HCl) for 2 h. After reaction, the heat treatment process is necessary to make hydrogenated powder homogenous. For the LaFe 11.8 Si 1.2 micronized ( 11.8 Si 1.2 ).
