Tellurium is used as a carbide stabilizer in white cast iron to make the surface strong and wear-resistant. Lead containing a small amount of tellurium can improve the corrosion resistance, wear resistance and strength of the material and can be used as a sheath for submarine cables. It is used to make battery poles and print type. Tellurium can be used as an additive for petroleum cracking catalyst and catalyst for preparing ethylene glycol. Tellurium oxide is used as coloring agent for glass. High purity tellurium can be used as an alloy component of thermoelectric materials. Bismuth telluride is a good refrigerant material. Tellurium and some tellurium are semiconductor materials. Ultra pure tellurium single crystal is a new type of infrared material.

In addition, tellurium is a delayed detonation fuse in timing explosive. Tellurium can be used as a raw material for the manufacture of fungicides. Tellurium can also extract isotopes of iodine in medical treatment to cure thyroid diseases. At the same time, it can be used as catalyst for petroleum cracking, brightener of electroplating bath, coloring material of glass, added to steel to increase its ductility, added to lead to increase its strength and corrosion resistance. Tellurium and its compounds are also semiconductor materials.
