采用OS法制备了Nb-Ti-Ni透氢合金粉末，该过程是通过电解CaCl2熔融产生的Ca同时还原Nb、Ti和Ni氧化物的混合物。反应机理证实，在反应初期易形成bcc-(Nb，Ti)相，然后由NbO和Ti2O等较低氧化物生成B2-TiNi相。随着电荷量的增加，合成合金的氧含量显著降低到0.27质量%。这三种元素在宏观层面上是均匀分布的。
A Nb–Ti–Ni hydrogen permeable alloy was synthesized as a powder using the OS process, which involves the simultaneous reduction of a mixture of Nb, Ti, and Ni oxides by Ca that is generated from molten CaCl2via electrolysis. The mechanism confirmed that a BCC-(Nb, Ti) phase easily formed at an early stage of the reaction followed by the generation of a B2-TiNi phase from the lower oxides such as NbO and Ti2O. The oxygen content of the synthesized alloy decreased significantly to 0.27mass% with increased electric charge. The three elements were uniformly distributed at the macroscopic level.
