LaNi5 is an intermetallic compound with a CaCu5 structure. It belongs to the hexagonal crystal system.[4] It can be oxidized by air above 200°C, and react with hydrochloric acid, sulfuric acid or nitric acid above 20°C.[5] LaNi5 can be used as a catalyst for hydrogenation reactions.[6][7]
Other alloys
In addition to LaNi5, there are other alloys such as La2Ni7, LaNi2, LaNi3, La2Ni3, LaNi, and La3Ni, and nonstoichiometric alloys such as LaNi2.286 (tetragonal, space group I4̄2m).[8] The nickel atoms in LaxNiy can also be replaced by other atoms, such as LaNi2.5Co2.5.[9]
