· NaAuO2

Sodium gold oxide (NaAuO₂) is an inorganic ceramic compound containing gold in an oxidized state, belonging to the class of mixed-metal oxides. While not widely commercialized in high-volume engineering applications, this material is primarily of interest in research contexts for catalysis, electrochemistry, and advanced materials development, where its gold content and oxide chemistry offer potential advantages in specialized chemical processes. Engineers might consider NaAuO₂ when conventional catalysts prove insufficient for demanding oxidation reactions or when gold's chemical reactivity in a ceramic matrix provides unique selectivity or stability benefits.
