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 &#x3b3;-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.

[object Object]

An electromagnetic induction heat device to heat a first metal mineral stone and a second mineral stone to form a melting mixture liquid without stifling. The device keeps a temperature of the melting mixture liquid between solidus and liquidus of binary alloy phase diagram of the first and second metal mineral stone, then an alloy with solid state precipitates from said melting mixture liquid.

Method and apparatus for manufacturing high-purity alloy

The present invention provides a method for manufacturing high-purity hydrogen storage alloy MgNi 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 &#x3b3;-phase MgNi hydrogen storage alloy is given. Then high-purity &#x3b3;-phase MgNi hydrogen storage alloy with atomic ratio of 2:1, no other phases, and with excellent hydrogen absorption-desorption dynamics is given.
