Application

1. Semiconductors: Tellurium is used in compound semiconductors, such as cadmium telluride (CdTe) and bismuth telluride (Bi2Te3), which are essential materials in thermoelectric devices and solar cells.

2. Thermoelectric Materials: Tellurium-based compounds like bismuth telluride (Bi2Te3) are widely used in thermoelectric generators and coolers due to their ability to convert heat into electrical energy and vice versa.

3. Solar Cells: CdTe is a highly efficient material used in thin-film photovoltaic cells, which are key components of solar panels. Tellurium is critical in CdTe solar cells due to its ability to absorb sunlight effectively.

4. Metallurgy: Tellurium is added to steel, copper, and lead alloys to improve their machinability, strength, and corrosion resistance. In lead-acid batteries, tellurium helps enhance battery life and performance.

5. Optical Storage Devices: Tellurium is used in the production of rewritable optical discs such as CDs, DVDs, and Blu-ray discs, where tellurium-based phase-change materials are essential for data storage.

6. Catalysts and Chemical Processes: Tellurium is used as a catalyst in certain chemical reactions, including in the vulcanization of rubber and the manufacturing of synthetic fibers.
