Abstract

The chemical stability and electrochemical properties of LaNiO3-δ were measured by various temperatures and oxygen partial pressures p(O2). The chemical stability of LaNiO3-d has been determined by coloumetric titration and high temperature X-ray diffraction. The LaNiO3-d has a short range of chemical stability over the p(O2). At the high temperature and low p(O2) (10-4 bar) the XRD patterns showed the NiO peaks, where Ni3+ was reduced into Ni2+. On the other side, the study on the electrochemical impedance spectroscopy indicates that it has relatively high area specific conductivity even though it has a short range of chemical stability over the p(O2).
