Abstract:

The phase equilibria and crystal structures of mixed oxides in the ternary system La2O3-Mn3O4-NiO are studied at 1100 degrees C in air. The projection of the La-Mn-Ni-O phase diagram at 1100 degrees C and p(O2) = 0.21 x 10(5) Pa onto the metal-composition triangle is found to comprise 12 phase fields. The lattice parameters of La2NiO4 (sp. gr. I4/mmm), La3Ni2O7 (sp. gr. Cmcm), La4Ni3O10 (sp- gr. Cmca), and La1+xMn1-x-yNiyO3 solid solutions (sp. gr. Pnma, -0.04 <= x <= 0.05, 0 <= 0.4) are determined. The composition stability limits of La4Ni3-yMnyO10 solid solutions are 0 < y <= 0.05. With increasing Ni concentration in La1-xMn1-x-yNiyO3, the metal nonstoichiometry decreases from -0.04 <= x <= 0.05 at y = 0 to x = 0 at y = 0.4.
