· JVASP-13375· Na4C2O5

Na4C2O5 is an inorganic ceramic compound belonging to the family of sodium oxycarbonates, characterized by a crystal structure combining sodium cations with carbonate and oxide anions. This material exists primarily in research and experimental contexts rather than as an established industrial ceramic, with potential applications in solid-state chemistry, thermal energy storage systems, and advanced ceramic formulations where the unique sodium-carbon-oxygen chemistry offers novel properties.
