· JVASP-58865· Na3AuO2

Na3AuO2 is an ionic ceramic compound containing sodium, gold, and oxygen, belonging to the family of mixed-valence oxide ceramics with potential electrochemical properties. This is primarily a research material rather than an established commercial ceramic; it is of interest in solid-state chemistry and materials research for its unusual gold oxidation state and crystal structure. The material family shows promise in electrochemical applications and fundamental studies of gold chemistry in oxide systems, though practical engineering applications remain limited to specialized research contexts.
