Interaction of SrTi0.65Fe0.35O3-δ with LaNi0.6Fe0.4O3-δ, La0.6Sr0.4Co0.2Fe0.8O3-δ and Ce0.8Gd0.2O2-δ
Abstract
Iron doped strontium titanates SrTi1-xFexO3-δ are perovskites of versatile properties. They can be used in solid oxide fuel cells or high temperature oxygen sensors. Their reactivity with electrolyte materials, cathode buffer layer materials, other cathode materials or current collector layers has not been fully tested. In this study we use X-ray diffraction to check SrTi0.65Fe0.35O3-δ compatibility with Ce0.8Gd0.2O2-δ (used as electrolyte or cathode-YSZ electrolyte buffer layer), LaNi0.6Fe0.4O3-δ (typical current collector) and La0.6Sr0.4Co0.2Fe0.8O3-δ (typical cathode). It is shown that SrTi0.65Fe0.35O3-δ reactivity with Ce0.8Gd0.2O2-δ and La0.6Sr0.4Co0.2Fe0.8O3-δ is negligible up to 1400°C, while reaction with LaNi0.6Fe0.4O3-δ occurs between 1000°C and 1200°C leading to the formation of NiO, SrLaFaO4 and possibly La4Ni3O10.
