Apparatus for continuously manufacturing stoichiometric Mg2Ni hydrogen storage compound

An apparatus for continuously manufacturing stoichiometric Mg2Ni hydrogen storage compound, comprising:

• a vacuum chamber filled with an inert gas;
• a first crucible, set in the vacuum chamber, for holding a raw material of magnesium;
• a heating device, surrounding the first crucible, for heating the first crucible loaded with the raw material of magnesium and melting the raw material of magnesium to a magnesium liquid;
• a material feeding tube, set in the vacuum chamber, for adding nickel powders to the first crucible loaded with the magnesium liquid;
• a stirring device, set in the vacuum chamber and above the first crucible, for stirring the magnesium liquid to make the nickel powders fast melt in the magnesium liquid;
• a hoist mechanism, set in the vacuum chamber for hanging the first crucible into or out of the heating device;
• and
• a second crucible, set in the vacuum chamber, and on one side of the first crucible,
• wherein the heating device is further used for heating the first crucible loaded with a mixture of the nickel powders and the magnesium liquid to produce a magnesium-nickel liquid and controlling the heating temperature of the heating device to fall within a temperature range;
• a stoichiometric Mg2Ni hydrogen storage compound is precipitated from the magnesium-nickel liquid;
• a residual liquid in the first crucible is separated from the precipitated stoichiometric Mg2Ni hydrogen storage compound and poured from the first crucible to the second crucible;
• and
• the stoichiometric Mg2Ni hydrogen storage compound in the first crucible is cooled and drawn out from the first crucible after cooling.
