Tellurides And Telluride Compounds

About Tellurides and Tellurium Compounds

Tellurides are compounds derived from the telluride anion ^Te2-. Since tellurium is in group 16 of the periodic table, it is classified as a chalcogen. Therefore, tellurium compounds are categorised as chalcogenides.

Alkali and alkaline earth chalcogenides are generally colourless and water‐soluble compounds. They are used primarily as reagents in chemical synthesis. In contrast, transition metal chalcogenides exhibit covalent bonding and possess defined electronic and optical properties. Many of these compounds display bright colours.

Categories of Tellurides and Tellurium Compounds:

Bismuth telluride (Bi2Te3) Thermoelectric Materials: Bismuth telluride (Bi2Te3) is a thermoelectric material that converts heat into electricity and vice versa. Recorded efficiencies reach up to 5%. Thermoelectric devices based on Bi2Te3 are used for power generation and waste heat recovery.

Thermoelectric Materials from Lead telluride (PbTe): Lead telluride (PbTe) is a recognised thermoelectric material that operates effectively at higher temperatures. Performance improvements of up to 7% have been observed at elevated temperatures. PbTe‐based thermoelectric generators are employed in various industrial and automotive applications.

Photovoltaic Materials from Cadmium telluride (CdTe): Cadmium telluride (CdTe) is a semiconductor compound commonly used in thin‐film photovoltaic solar cells. CdTe solar cells offer an economically viable and efficient solution for harnessing solar energy. Energy conversion rates have reached approximately 18% in controlled tests.
