Copper ditelluride is an inorganic compound with the chemical formula CuTe 2.It is a superconductor with a C18 structure and a transition temperature of 1.3 K. [2] CuTe 2 crystals can be synthesized by reacting elemental copper and tellurium with a molar ratio of 1:2 at a pressure of 65 kbar for 1–3 hours at 1000–1200 °C, followed by slow cooling.

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 ...
The telluride iodides are chemical compounds that contain both telluride ions (Te 2−) and iodide ions (I −). They are in the class of mixed anion compounds or chalcogenide halides. [1] Tellurium does not normally bond with iodine, but can form many different units with bonds to other tellurium atoms.
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. The redox potential is −1.14 V. [2] Te(s) + 2 e − ↔ Te 2−
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 telluride: weissite. [1] Tellurium copper is not suited to welding, but it can be welded with gas shielded arc welding or resistance welding.
