· JVASP-141585· Ca5Mn4O9

Ca₅Mn₄O₉ is a mixed-valent calcium-manganese oxide ceramic compound belonging to the perovskite-related oxide family. This material is primarily of research and development interest rather than an established commercial ceramic, studied for its electronic and magnetic properties in contexts where manganese oxidation state manipulation offers functional advantages. It is investigated for electrochemical applications and advanced ceramics where tailored redox behavior and ionic conductivity are desirable, offering potential alternatives to conventional transition metal oxides in specific technological niches.
