Copper(II) telluride is an inorganic compound with the chemical formula CuTe that occurs in nature as a rare mineral vulcanite.
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
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 ...
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.
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.

Structure of tellurium tetrachloride, tetrabromide and tetraiodide. The +2 oxidation state is exhibited by the dihalides, TeCl 2, TeBr 2 and TeI 2.The dihalides have not been obtained in pure form, [3]: 274 although they are known decomposition products of the tetrahalides in organic solvents, and the derived tetrahalotellurates are well-characterized:
