Sodium tellurite is an inorganic tellurium compound. It is a weak reducing agent. Sodium tellurite is an intermediate in the extraction of the element, tellurium; it is a product obtained from anode slimes and is a precursor to tellurium.
Sodium terllurite is an alkali tellurite that is majorly used in the formation of glasses due to its unique properties which include good transmittance, refractive index, and high chemical resistance. It can be used as a tellurite source for the preparation of quantum dots.
