· JVASP-47641· Na2Sn2O3

Sodium stannate (Na2Sn2O3) is an inorganic oxide ceramic compound containing tin and sodium, belonging to the stannate family of functional ceramics. While primarily investigated in research contexts, this material has potential applications in optoelectronics, catalysis, and sensor technologies due to tin oxide's semiconducting properties when modified with alkali dopants. Its distinction lies in combining tin's catalytic and electronic activity with sodium's role in phase formation and ionic conductivity, making it relevant for developers exploring alternatives to pure tin oxide systems in niche industrial applications.
