Abstract: As the solid foundation of building ternary phase relations, Ni-Ga binary phase relations at 700℃were experimentally determined by X-ray powder diffraction and the confusion in the previous reports was clarified. The arc-melting was adopted to prepare the samples and ensure the full mixing of starting elements. Five intermetallic compounds were obtained, i.e., Ni1-xGax, Ni3Ga, Ni13Ga9, NiGa and Ni2Ga3, but Ni5Ga3, Ni3Ga2, Ni3Ga4 and NiGa4 phases were not found in experiment. Their lattice parameters and the powder X-ray diffraction patterns including thed-value and the indices of crystallographic planes were given as a reference to determine exact ternary phase relations of Ni-Ga-Sb(As).
