Abstract

The hydriding and dehydriding reactions occurring in mixtures of lithium and magnesium nitrides (Li3N and Mg3N2) were investigated for the first time in fixed composition ratios. A mixture of Li3N-20 at. % Mg3N2 after heat treatment at 833 K was hydrogenated at 523 K in 35 MPa according to the following overall reaction: 4Li3N + Mg3N2 + 12H2 ⇔ 12LiH + 3Mg(NH2)2. This reaction is one of the candidates for reversible hydrogen-storage functions in which 9.1 mass % of hydrogen can be stored in the solid state.
