Tellurium is a chemical element; it has symbol Te and atomic number 52. It is a brittle, mildly toxic, rare, silver-white metalloid. Tellurium is chemically related to selenium and sulfur, all three of which are chalcogens. It is occasionally found in its native form as elemental crystals.
Copper(I) telluride is an inorganic compound with the chemical formula Cu 2 Te. It can be synthesized by reacting elemental copper and tellurium with a molar ratio of 2:1 at 1200 °C in a vacuum. [3] Cu 2 Te has potential applications in thermoelectric elements and in solar cells, where it is alloyed with cadmium telluride to create a ...
ASTM specification B301 has 0.5% tellurium; at concentrations of up to 0.75% machinability is improved while electrical conductivity and hot working behavior is maintained. Mechanical properties are similar to tough pitch copper , while machinability is similar to brass - the hardness of the alloy is increased by precipitation of the copper ...
The telluride ion is the anion Te 2− and its derivatives. It is analogous to the other chalcogenide anions, the lighter O 2−, S 2−, and Se 2−, and the heavier Po 2−. [1]In principle, Te 2− is formed by the two-e − reduction of tellurium.

Tellurium is a semiconductor with an electrical conductivity of around 1.0 S•cm −1 [388] and a band gap of 0.32 to 0.38 eV. [389] Liquid tellurium is a semiconductor, with an electrical conductivity, on melting, of around 1.9 × 10 3 S•cm −1. [389] Superheated liquid tellurium is a metallic conductor. [390]
