· JVASP-30299· Mn5O9F

Mn5O9F is a mixed-valence manganese oxide fluoride ceramic compound that combines manganese oxides with fluorine, creating a complex anionic structure. This material belongs to the family of manganese-based oxyfluorides, which are of significant research interest for applications requiring specific electronic, magnetic, or catalytic properties. While not yet a commodity material in widespread industrial use, compounds in this class show promise in battery technology, catalysis, and advanced functional ceramics where the fluorine substitution can modify electronic structure and ion mobility compared to conventional oxides.
