Today, most tellurium is obtained as a byproduct of mining and refining copper. Tellurium is a semiconductor and is frequently doped with copper, tin, gold or silver. Tellurium is also used to color glass and ceramics and is one of the primary ingredients in blasting caps.Tellurium is primarily used as an alloying agent.Small amounts of tellurium are added to copper and stainless steel to make them easier to machine and mill.ellurium is also used to color glass and ceramics and is one of the primary ingredients in blasting caps.
