    摘要: The present invention provides a method and apparatus for manufacturing high-purity hydrogen storage alloy Mg2Ni applicable to industry and capable of manufacturing continuously. First, raw materials of magnesium-nickel with weight percentage of nickel between 23.5 and 50.2 are heated, melt, and mixed uniformly. Cool the magnesium-nickel liquid and control the temperature to be above the solidification temperature and below the liquification temperature in the phase diagram of magnesium-nickel. By making advantage of segregation principle in phase diagrams, solid-state high-purity γ-phase Mg2Ni hydrogen storage alloy is given. The residual waste magnesium-rich liquid in the crucible is poured to another independent crucible, and switch with the position of the crucible originally containing the γ-phase Mg2Ni hydrogen storage alloy. Then, new raw materials of magnesium and nickel are added and heated. Repeat the smelt steps described above continuously, and a continuous manufacturing method is introduced. After the original crucible is cooled, the solid substances at the bottom of the crucible can be tapped down without further special treatments. Then high-purity γ-phase Mg2Ni hydrogen storage alloy with atomic ratio of 2:1, no other phases, and with excellent hydrogen absorption-desorption dynamics is given.
