Applications

Tellurium powder is used in telluride compounds, thermal analysis test cup, precision casting, quenching, special Steel/Aluminum additives, refrigeration materials, infrared detectors, test instruments, chemical vapor deposition and physical vapor deposition processes. Tellurium is often used as an additive to steel and it is often alloyed to aluminum, copper, lead or tin. Tellurium is added to lead to improve its durability, strenght and resistence to corrosion. It can be used for cast iron, ceramics, blasting caps, etc.
