Abstract

NiO–LSGM reactivity during sintering at high temperatures in air leads to the formation of LaNiO3-type phase which is found to be insulating for oxygen ions. XRD analysis of the NiO-LSGM samples after sintering at 1350 °C in air showed cubic (Pm-3m) LaNiO3-based phase with a lattice parameter of 3.856 Å in addition to the cubic structure of LSGM20-17. STEM/EDX analysis of the NiO– LSGM interface showed the presence of a Ni-containing perovskite phase (La, Sr) (Ga, Ni, Mg)O3 –x in the diffusion layer of LSGM. The probable composition of the LaNiO3- type phase that formed during sintering is discussed.
