· JVASP-55526· Na2Te2O7

Sodium tellurite (Na₂Te₂O₇) is an inorganic ceramic compound belonging to the tellurite oxide family, characterized by a structure combining sodium, tellurium, and oxygen. This material is primarily of research and specialized industrial interest, with applications in optical glass formulations, nonlinear optics, and solid-state laser host materials, where tellurite compounds offer advantages in infrared transmission and optical nonlinearity compared to conventional silicate ceramics. Na₂Te₂O₇ is also investigated for potential use in thermal energy storage systems and as a precursor phase in advanced ceramics development.
