Subsolidus phase equilibria in the La_2O_3-Ga_2O_3-NiO system

摘要

Subsolidus equilibria in air in the La_2O_3 -Ga_2O_3-NiO system were studied with the aim of obtaining information on possible interactions between a LaGaO_3-based solid electrolyte and NiO during preparation of the anode in solid oxide fue1 cel1s (SOFC). No ternary compound was found. The tie lines are between LNGa_2O_7 and La_2NiO_4, LaGaO_3 and La2NiO_4, LaGaO_3 and NiO, and LaGaO_3 and NiGa_2O_4.
