Abstract

Properties of a novel hydrogen storage alloy system, Mg-Zn-Ni (Mg:Zn=7:3), were investigated by pressure-composition isotherm measurements, thermogravimetry-differential thermal analysis and X-ray powder diffraction. Mg7Zn3 has a low melting point, near 600 K, but the hydriding reaction proceeds at more than 620 K. At least a part of the alloy melted during hydrogenation. The hydride formed was MgH2 and no new hydride phases have been observed. Addition of nickel to the Mg-Zn alloy improved the reaction kinetics.
