A rare nonmetallic element, analogous to sulphur and selenium, occasionally found native as a substance of a silver-white metallic luster, but usually combined with metals, as with gold and silver in the mineral sylvanite, with mercury in Coloradoite, etc. Symbol Te. Atomic weight 125.2.
A semi metallic element that occurs in a silvery white brittle crystalline form of metallic luster. Used especially in alloys
Like selenium it is used, usually in conjunction with lead, to improve the machinability of steel.
Its main use in the steel industry is as an additive in leadbearing freecutting steels to further improve their machinability. Its presence in the steel is either within the manganese sulphide particles, where it is partially soluble, or as particles combined with lead or manganese. For certain applications it offers significant improvements in machinability but the added cost is a factor that should be taken into account.
Rare silvery-white chemical element close to the metals (it is a non-metal).
Tellurium is added to steel to modify sulfide type inclusion size, morphology and distribution. The resulting sulfide type inclusions are finer and remain ellipsoidal in shape following hot working, thereby improving transverse properties.
a brittle silver-white metalloid element that is related to selenium and sulfur; it is used in alloys and as a semiconductor; occurs mainly as tellurides in ores of copper and nickel and silver and gold
A brittle, silvery-white metallic element usually found in combination with gold and other metals, produced commercially as a byproduct of the electrolytic refining of copper and used to alloy stainless steel and lead, in ceramics, and, in the form of bismuth telluride, in thermoelectric devices.
Tellurium (IPA: ) is a chemical element that has the symbol Te and atomic number 52. A brittle silver-white metalloid which looks like tin, tellurium is chemically related to selenium and sulfur. Tellurium is primarily used in alloys and as a semiconductor.
