| 專利名稱 | Method and apparatus for manufacturing high-purity hydrogen storage alloy Mg2Ni | | 專利證號 | US7651546B2 | | 國別 | 美國 | | 獲證日期 | 2010-01-26 | | 專利摘要 | The present invention provides a method for manufacturing high-purity hydrogen storage alloy Mg 2Ni 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. 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.

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 gamma-phase Mg2Ni hydrogen storage alloy is given. Then high-purity gamma-phase Mg2Ni hydrogen storage alloy with atomic ratio of 2:1, no other phases, and with excellent hydrogen absorption-desorption dynamics is given. | IPC國際分類號 | C22B002622 |
