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 ...
6. In the +6 oxidation state, the –OTeF 5 structural group occurs in a number of compounds such as HOTeF 5, B(OTeF 5) 3, Xe(OTeF 5) 2, Te(OTeF 5) 4 and Te(OTeF 5) 6. [4] The square antiprismatic anion TeF 2− 8 is also attested. [5] The other halogens do not form halides with tellurium in the +6 oxidation state, but only tetrahalides (TeCl 4 ...
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 ...
Copper telluride may refer to: Weissite, a mineral, Cu 2−x Te; Rickardite, a mineral, Cu 7 Te 5 (or Cu 3−x (x = 0 to 0.36) Te 2) Copper(I) telluride, Cu 2 Te; Copper(II) telluride, CuTe, which occurs as the mineral vulcanite; Copper ditelluride, CuTe 2; Tellurium copper, copper alloy with tellurium

Tellurium generally forms compounds in which it has an oxidation state of −2, +4 or +6. The +4 state is the most stable. [ 381 ] Tellurides of composition X x Te y are easily formed with most other elements and represent the most common tellurium minerals.
6. In the +6 oxidation state, the –OTeF 5 structural group occurs in a number of compounds such as HOTeF 5, B(OTeF 5) 3, Xe(OTeF 5) 2, Te(OTeF 5) 4 and Te(OTeF 5) 6. [46] The square antiprismatic anion TeF 2− 8 is also attested. [38] The other halogens do not form halides with tellurium in the +6 oxidation state, but only tetrahalides (TeCl ...
The Seebeck coefficient (also known as thermopower, [1] thermoelectric power, and thermoelectric sensitivity) of a material is a measure of the magnitude of an induced thermoelectric voltage in response to a temperature difference across that material, as induced by the Seebeck effect. [2]
