Sr3Ti1.6Nb0.4O7 is a mixed-metal oxide ceramic belonging to the perovskite-related family, combining strontium, titanium, and niobium oxides in a layered structure. This material is primarily investigated in research settings for high-temperature applications where thermal and electrical properties can be engineered through compositional tuning; the niobium substitution on the titanium site modifies defect chemistry and ionic transport characteristics compared to parent strontium titanate phases. Industrial interest centers on solid oxide fuel cells, oxygen sensors, and thermal barrier coating systems where the material's combination of ionic conductivity and structural stability at elevated temperatures offers potential advantages over conventional alternatives.
