摘要：

Phase equilibria in the LaNiO system at 1200°C were established at oxygen partial pressures ranging from 1 to 10-12.00 atm. In this system, La2NiO4 and La6Ni5O15 are stable as the ternary oxide. The latter is probably a new compound and its spacings and relative intensities are presented. La3Ni2O7 and La4Ni3O10 are not stable. La2NiO4 has nonstoichiometric compositions, as is well known, and the relationship between the composition and the oxygen partial pressure is presented. The standard Gibbs energies of the reactions which appear in the system are obtained. © 1990.
