· JVASP-49233· NaSe2

Sodium diselenide (NaSe₂) is an ionic ceramic compound belonging to the alkali metal chalcogenide family, combining sodium with selenium in a 1:2 stoichiometric ratio. While primarily of research interest rather than established industrial production, this material is studied for potential applications in solid-state chemistry, particularly in ionic conductivity studies and as a precursor for selenide-based functional materials. NaSe₂ represents an underexplored compound within the broader class of alkali chalcogenides, which have attracted attention for energy storage, photovoltaic, and solid electrolyte applications where selenium-based systems offer unique electronic and ionic transport properties.
