Description
Niobium nickel alloy is an alloy formed between niobium and nickel. There are various alloy phases such as LaNi5, La2Ni7, LaNi2, LaNi3, La2Ni3, LaNi and La3Ni, among which LaNi5 is most common. Lanthanum nickel alloy can absorb a large amount of H2 to form a metal hydride, which can be used as a hydrogen storage material.
