Abstract
The subsolidus phase relations in the La-Fe-Al-O system were investigated f or solid oxide fuel cell (SOFC) applications. Five compounds, LaAlO3, LaAl1 1O18, LaFe12O19, AlFeO3, and LaFeO3, coexist in the La-Fe-Al-O system at 13 80 degreesC in air. The microstructure and composition of the samples were studied by x-ray diffractometry and scanning electron microscopy. Based on experimental evidence, a phase diagram of the La2O3-Al2O-Fe2O3 system has b een proposed.
