· Na4I2O

Na₄I₂O is an iodine-containing ceramic compound composed of sodium, iodine, and oxygen. This material belongs to the family of mixed-valence ionic ceramics and remains primarily in the research and developmental stage, with limited industrial adoption. The compound is of interest in solid-state chemistry and materials science for its potential applications in ion-conducting systems and as a precursor phase in synthesis of other functional ceramics, though specific engineering applications at scale have not been widely established.
