Hydrogen storage Mg2Ni alloy produced by induction field activated combustion synthesis

It is difficult to obtain pure Mg2Ni alloy by conventional melting method because of the large difference in vapor pressure and melting point between Mg and Ni. However, Mg2Ni with high purity and fine properties as a hydrogen storage material was successfully synthesized from elemental Mg and Ni powders by Induction Field Activated Combustion Synthesis (IFACS). The IFACSed Mg2Ni showed convenient hydrogen properties as same as the reference. The effect of Mechanical Grinding (MG) on the hydrogen storage behavior in Mg2Ni is also described. The MG process developed the applicability of Mg2Ni as a hydrogen storage material by decreasing the absorption pressures and enhancing the reaction kinetics.
