About Tellurium

Tellurium is a metalloid with atomic number 52 that belongs to the chalcogen group. Cadmium telluride is used in thin film solar cells, while bismuth telluride is used in thermoelectric devices that convert between heat and electrical energy. Tellurium also improves the machinability of selected metal alloys, connecting its chemistry to both energy materials and metallurgy.
