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 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 ...
Dysprosium(III) telluride reacts with copper(II) telluride at high temperature to obtain phases such as DyCuTe 2, DyCu 5 Te 4, and Dy 7 Cu 3 Te 12. [2] It and cadmium telluride can form CdDy 2 Te 4 at high temperatures: [3] Dy 2 Te 3 + CdTe → CdDy 2 Te 4
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 tellurium oxides and hydrated oxides form a series of acids, including tellurous acid (H 2 TeO 3), orthotelluric acid (Te(OH) 6) and metatelluric acid ((H 2 TeO 4) n). [9] The two forms of telluric acid form tellurate salts containing the TeO 2– 4 and TeO 6− 6 anions, respectively. Tellurous acid forms tellurite salts containing the ...
