Abstract
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. Through this apparatus, a 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 and the rest waste magnesium-rich liquid can be recycled.
