In this paper, electrolysis tests were carried out for analyzing the gas purities evolving from the cup-shaped Fe-Ni-Al2O3 anodes, which were made by slip casting. The oxygen purity of the collecting anodic gas detected by Orsat apparatus was in an interval of 98–100%. SEM and XRD results showed that Fe-Ni-Al2O3 anode surface formed a layer that consisted of FeAl2O4, NiO, and Al2O3 mainly, as well as small amounts of metal phase Ni3Al.
