The present invention provides an apparatus for manufacturing stoichiometric Mg2Ni compound applicable to industry and capable of manufacturing continuously. The apparatus mainly comprises: a vacuum chamber, comprising a material feeding tube; a first crucible, set in the vacuum chamber; a heating device, set on the first crucible; a stirring device, set in the vacuum chamber, and above the first crucible; and a second crucible, set in the vacuum chamber, and on one side of the first crucible. The present invention also discloses a method to manufacture stoichiometric γ-phase Mg2Ni hydrogen storage compound. Through this apparatus and method, 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 compound. 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 stoichiometric γ-phase Mg2Ni hydrogen storage compound with an exactly atomic ratio of 2:1, without other phases, and with excellent hydrogen absorption-desorption dynamics is given.
