Tellurium is one of the most rare, stable and solid elements in the earth’s crust. Generally extracted from anode sludge produced during the refining of copper, tellurium is classified as a metalloid - or semi-metal - meaning it has some properties of both metals and non-metals. Due to its unique thermo-electric properties, tellurium is used in a variety of applications, including cadmium telluride (CdTe) photovoltaic cells.
SMI Ltd. is a supplier of tellurium metal ingots, tellurium powder and tellurium dioxide (TeO2). Please contact us to purchase tellurium, and to discuss current prices or your specific requirements.
Tellurium Metal Ingots99.5% - 99.99% min.
Tellurium is widely used in metallurgical and thermo-electronic applications. Alloyed with copper, tellurium inhibits hydrogen embrittlement and increases machineability. The metal also has a high level of conductivity, making it ideal...
