Tellurium Powder

Tellurium is a chemical element with the symbol Te and atomic number 52. It is a silvery-white, brittle, slightly toxic, rare metalloid. Tellurium is chemically related to selenium and sulfur. Occasionally it is found in the native form as elemental crystals. Tellurium is much more common in the universe as a whole than on Earth. Its extreme rarity in comparison to platinum crust is due in part to its high atomic number, but also the formation of a volatile hydride was lost due to space as a gas during the hot planet nebula formation.

Compounds containing tellurium were discovered in 1782 in a gold mine in Zlatna, Romania, by the Austrian mineralogist Franz-Joseph Müller von Reichenstein, although it was Martin Heinrich Klaproth who called the new element in 1798, after the Latin word for “land”. we. The gold minerals of tellurium are the most important natural compounds of gold. However, they are not a commercially important tellurium source, which is normally extracted as a by-product of copper and lead production.

Commercially, the main use of tellurium is copper and steel alloys, where it improves workability. Solar panel applications and semiconductor CoW also consume a considerable part of tellurium production.

Tellurium has a biological function, although mushrooms can use in place of sulfur and selenium amino acids such as telurocisteína and selenomethionine. In humans, tellurium is partially metabolized in dimethyl tellurium (CH3) 2TE, a gas with an odor exhaled garlic agile of victims of poisoning or tellurium exposure.
