Description

一般描述

Tellurium is anon-radioactive and heaviest member of the chalcogen family. It has a widerange of oxidation states, from -2 to +6. It is widely used in the fields ofmetallurgy and electronics.

应用

碲与氢氧化钾结合，介导了芳香族羰基化合物的定量频哪化。

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.
