If tellurium metal is the desired end product, the refined tellurium compounds can be reduced to produce metallic tellurium, typically using carbon or hydrogen as a reducing agent. Forming Alloys In some cases, tellurium is alloyed with other metals, such as copper or stainless steel, to enhance their properties for specific applications.
Tellurium, element 52, is a metalloid used at low concentrations in the formulation of various steel, rubber, and ceramic products, among others. Tellurium toxicity is rare (Larner 1995 ), but it is of interest as a model system for study of the type of metabolic insult that can lead to specific demyelination.
