Na2 I2 O4 F4

Na2I2O4F4 is a mixed-anion ceramic compound containing sodium, iodine, oxygen, and fluorine—a rare compositional system that combines halide and oxide chemistry. This material belongs to the family of fluoroiodates and related mixed-halide oxides, which remain largely in the research phase; the compound is not commonly encountered in established industrial applications, but represents exploration into ion-conducting or structural ceramics with potential relevance to solid-state ionics and advanced ceramic chemistry.
