Abstract

Subsolidus equilibria in air in the La2O3–Ga2O3–NiO system were studied with the aim of obtaining information on possible interactions between a LaGaO3-based solid electrolyte and NiO during preparation of the anode in solid oxide fuel cells (SOFC). No ternary compound was found. The tie lines are between La4Ga2O7 and La2NiO4, LaGaO3 and La2NiO4, LaGaO3 and NiO, and LaGaO3 and NiGa2O4.
