Synthesis and hydrogenation properties of Mg–3 mol%LaNi3 composite prepared under an external magnetic field

The Mg–3 mol%LaNi3 composition was successfully prepared by different techniques, namely, the composite was synthesized by hydrogen combustion synthesis (HCS) with and without an external high magnetic field. The hydrogen storage capacities and hydriding/dehydriding (H/D) rates of the two composites at different temperatures were evaluated and their structures and morphologies were examined. Our main goal in this study is how to control the process of HCS by the external high magnetic field and to investigate its effect on the hydrogenation properties of the composite and analyze these changes from the relationship between the microstructure and crystalline state and the energy injected into the composite from the external high magnetic field.
