Tellurium is a brittle metalloid element with semiconducting properties, commonly used in thermoelectric devices, photovoltaic applications, and as a dopant in specialty alloys and glasses. It is valued in industries requiring thermal-to-electric energy conversion and infrared optical components, where its unique electronic and optical characteristics provide advantages over conventional alternatives. Engineers select tellurium primarily for high-temperature thermoelectric generators, solar cells, and specialized optical systems where its combination of thermal and electrical behavior justifies its cost and handling complexity.

Export Control
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
