Used as a precursor in the synthesis of tellurium-based nanomaterials and specialty glasses with unique optical properties. Employed in electroplating baths to produce tellurium-containing alloys with improved corrosion resistance and wear performance. Serves as an oxidizing agent in selective organic oxidation reactions, particularly in laboratory-scale synthesis of fine chemicals. Investigated for use in advanced battery systems as a component in cathode materials due to its redox activity. Also utilized in analytical chemistry for the detection and determination of certain reducing agents.
