Mn4 O3 F5

Mn₄O₃F₅ is a mixed-valence manganese oxide fluoride ceramic compound that functions as a semiconductor, combining the redox chemistry of manganese oxides with the structural and electronic properties conferred by fluorine substitution. This material is primarily of research and developmental interest rather than established commercial production, representing an emerging class of functional ceramics studied for electrochemical energy storage and catalytic applications where the manganese-fluorine interaction can modulate electronic properties and surface reactivity.
