· JVASP-98028· Na2Te2O5

Sodium tellurite (Na₂Te₂O₅) is an inorganic oxide ceramic compound belonging to the tellurite family of materials. This compound is primarily studied in research contexts for photonic and optical applications, where tellurite ceramics are valued for their high refractive index and broad infrared transmission window, distinguishing them from conventional silicate glasses. Industrial interest centers on potential use in fiber optics, infrared optical components, and electrochemical devices, though Na₂Te₂O₅ itself remains largely in development phases rather than mature production applications.
