Ce4 Dy1 O9
semiconductor· Ce4 Dy1 O9
Ce₄Dy₁O₉ is a rare-earth oxide ceramic compound combining cerium and dysprosium oxides, belonging to the fluorite-related oxide family used in advanced functional ceramics and solid-state applications. This material is primarily investigated in research contexts for solid oxide fuel cells (SOFCs), oxygen ion conductors, and thermal barrier coatings, where the mixed rare-earth composition offers tuned ionic conductivity and thermal stability compared to single-element rare-earth oxides. The dysprosium-doped ceria system is valued for its potential to enhance electrolyte performance and durability in high-temperature electrochemical devices.
