Tellurium is a light semi-metal of sliver-white color. It has got its name after the Latin word meaning earth. Tellurium is a toxic chemical element which has no importance to supporting living circle of living organisms on our planet. Uncombined, it can be found very rarely, thus mostly it is obtained from minerals and natural chemical compounds of this element. It is quite resistive to corrosion and does no dissolve in most of acids. Tellurium forms a few compounds which have a number of applications. It is used in alloys with lead, copper, and iron, to produce some parts of machinery and other durable parts. This chemical element is used for producing semi-conductors, solar panels, infrared sensors, and many other things. It is also used to process ceramics, tint glass, and vulcanize rubber.
