Tellurium Information

Silvery metalloid element of group 16. Eight natural isotopes, nine radioactive isotopes. Used in semiconductors and to a degree in some steels. Chemistry is similar to Sulphur. Discovered in 1782 by Franz Miller.

Used to improve the machining quality of copper and stainless steel products and to color glass and ceramics. Also in thermoelectric devices. Some is used in the rubber industry and it is a basic ingredient in manufacturing blasting caps.
