Fe5O2F8

Fe5O2F8 is an iron oxide fluoride ceramic compound combining iron oxides with fluoride anions in its crystal structure. This material belongs to the family of mixed-anion ceramics and appears to be primarily a research compound rather than an established industrial material; iron fluoride compounds are of interest in electrochemistry and solid-state ionics for their potential ionic conductivity and electrochemical properties. The incorporation of both oxide and fluoride ligands creates a unique crystal chemistry that researchers explore for energy storage, catalytic, and functional ceramic applications where conventional iron oxides or pure fluorides may be limiting.
