Tellurium is a chemical element with symbol Te and atomic number 52. It is a brittle, mildly toxic, rare, silver-white metalloid. Tellurium is chemically related to selenium and sulfur. It is occasionally found in native form, as elemental crystals. Tellurium is far more …

2.35 grams very shiny crystalline pieces of high purity tellurium – 99.9% purity in ampoule under argon This Tellurium shows beautiful crystalline structure. For semiconductor applications and for the advanced elements collection

But things become really exciting from a chemical point of view when less well-known elements are involved. An international research group from Germany and Finland discovered astonishing and beautiful molecular structures when, instead of oxygen or sulphur, they used the element tellurium…

Food (e.g. meat, dairy products, and cereals) is the main source of tellurium exposure in the general population. In the working environment, inhalational exposure predominates.

Tellurium was discovered by Franz Joseph Müller von Reichenstein, a Romanian mining official, in 1782. Reichenstein was the chief inspector of all mines, smelters and saltworks in Transylvania. He also had an interest in chemistry and extracted a new metal from an ore of gold, known as aurum album, which he believed was antimony .

This Tellurium Lake is north of the Fryingpan Valley (take Forest Road 501, above Ruedi Reservoir, to Forest Road 506 and follow it to the trailhead on Last Chance Creek. Forest Road 506, incidentally, is driveable in a passenger car.

Tellurium is a metalloid chemical element which is used in a variety of industries, primarily in the form of an additive to an assortment of compounds and alloys. It is relatively rare on the Earth's surface, and it is usually found in combination with other materials, such as gold. Tellurium can be isolated through chemical or electrolytic ...
