· Na1 W1 O3

Sodium tungstate (Na₁W₁O₃, more commonly written as Na₂WO₄) is an inorganic ceramic compound belonging to the tungstate family of materials, characterized by tungsten oxide networks with sodium ion incorporation. This material is primarily investigated in research contexts for electrochromic applications, photocatalysis, and solid-state ion-conducting systems, where its tunable bandgap and ionic mobility make it interesting for next-generation energy and optical devices. Compared to pure tungsten oxides, sodium tungstate offers modified electronic properties and lower sintering temperatures, making it potentially relevant for low-temperature processing in thin-film technologies, though it remains less established in high-volume industrial use than competing tungsten oxide formulations.
