· JVASP-13066· IO2F

IO2F is an iodine oxide fluoride ceramic compound with a mixed-valence iodine chemistry that places it in the family of halide-based ceramics. This material is primarily explored in solid-state chemistry and materials research contexts rather than established industrial production, where its unique ionic bonding and structural characteristics make it relevant for studying fluoride-ion conductivity and ceramic properties. IO2F and related iodine halide ceramics are investigated for potential applications in solid electrolytes, optical materials, and specialized chemical resistance applications where conventional oxide ceramics may be limited.
