TELLURIUM

Tellurium is a greyish-white semi-metallic element with a metallic lustre and the symbol Te. A semiconductor, it shows greater conductivity in certain directions, according to the alignment of the atoms. Tellurium is found in small quantities in its native state, but usually combined with metals such as tetradymite or bismuth telluride. Tellurium was named by Klaproth who examined it in 1798. Its compounds are toxic. The chief use of tellurium is in the vulcanisation of rubber. It is also used to colour glass, to increase the hardness of lead in battery plates, and to improve the machinability of stainless steel.
