Ba1 Cr4 O8
semiconductor· Ba1 Cr4 O8
Ba₁Cr₄O₈ is a barium chromium oxide ceramic compound belonging to the mixed-valence metal oxide family, where chromium exists in multiple oxidation states within a single crystalline structure. This material is primarily of research interest for electrochemical and optical applications, particularly as a potential cathode material in solid-state batteries and as a photocatalyst, though industrial adoption remains limited compared to more established chromium oxide ceramics. The compound's mixed-valence character and oxygen-deficient structure make it notable for ionic conductivity and catalytic properties in specialized high-temperature or electrochemical environments.
