Ｍｇ－Ｎｉ贮氢合金因其贮氢容量大、质量轻、原材料丰富、无污染和应用广泛而受到重视。传统的冶炼方法难于控制化学成分并在破碎之后需十余分钟的吸放氢活化处理。新近开发的燃烧合成工艺具有工艺时间短、设备简单、产品纯度高、节能等优点。为实现燃烧合成法的工业化，有必 Mg-Ni hydrogen storage alloy is valued for its large hydrogen storage capacity, light weight, rich raw materials, non-pollution and wide application. The traditional smelting method is difficult to control the chemical composition and after crushing more than ten minutes of hydrogen absorption and desorption activation. The newly developed combustion synthesis process has the advantages of short process time, simple equipment, high product purity and energy saving. In order to realize the industrialization of combustion synthesis method, it is necessary
