It has a widerange of oxidation states, from -2 to +6. It is widely used in the fields ofmetallurgy and electronics. Application Tellurium can be used as a precursor to prepare: - Tellurium-based nanomaterials for semiconductor application, such as CdTe nanoparticles via solvothermal synthesis. - Quantum dot solutions for fluorometric determination of bioactive compounds. - Thermoelectricmaterials, such as Cu4Mn2Te4 by the melting-quenching-SPS method. Tellurium, in combination with potassium hydroxide, mediates the quantitative pinacolization of aromatic carbonyl compounds.[1] |
