Ce2FeSe2O2

Ce₂FeSe₂O₂ is an experimental mixed-metal oxide ceramic containing cerium, iron, selenium, and oxygen. This compound belongs to the family of rare-earth transition-metal selenides and oxides, which are primarily investigated in materials research rather than established industrial production. The material is of interest in solid-state chemistry and functional ceramics research, where such mixed-valent systems are explored for potential applications in catalysis, solid-state ionics, and electronic/magnetic materials; however, it remains largely confined to laboratory-scale synthesis and characterization.
