Tungsten Telluride WTe2 Powder CAS 12067-76-4

About Tungsten Telluride WTe2 Powder:
Tungsten telluride (WTe2) is a transitional metal chalcogenide with a layered structure. In its orthogonal cell, the tungsten chain presents a one-dimensional distribution along the A axis of the tellurium layer. It is a kind of non-magnetic semi-metallic material.
Tungsten telluride (WTe2) is an inorganic semimetallic compound. Tungsten ditelluride is found to have very large magnetoresistance: at a magnetic field of 0.5 Kelvin, 60 teslas, the resistance increases by 13 million %. The resistance is proportional to the square of the magnetic field, showing unsaturation. This may be because the material is the first example of a compensating semi-metal where the number of movable holes is equal to the number of electrons tungsten ditelluride has a layered structure similar to many other transition metal halogen compounds, but its layered structure is distorted, and many of them share a honeycombed lattice that is difficult to identify in WTe2. Instead, tungsten atoms form zigzag chains that are thought to behave as one-dimensional conductors. Unlike electrons in other two-dimensional semiconductors, electrons in WTe2 can easily move between layers
The magnetoresistance effect in WTe2 decreases under pressure. When the pressure exceeds 10.5 GPa, the magnetoresistance disappears and the material becomes a superconductor. At 13.0 GPa, the superconducting transition occurs below 6.5 K.
Two – and three-layer thick WTe2 have also been observed to be polar metals, and the theory of electrical polarization with metallic behavior and conversion suggests that polarization is caused by vertical charge transfer between layers, which in turn is caused by interlayer sliding.

Performance of Telluride copper CuTe powder:

Copper telluride is a chemical substance with the molecular formula CuTe. Copper telluride is a black powder, which is relatively stable in air at room temperature. Copper telluride is not only an important inorganic material but also an excellent form of storing tellurium and copper resources. In the H2SO4 solution, replacing Te with Cu generates copper telluride, which separates tellurium from many metal ions and obtains a relatively high concentration. When Cu replaces Te, Te can be + 4 valences or + 6 valences, all of which can generate Cu 2 Te, that is, it is not affected by the valence state of tellurium. In the presence of an oxidizing agent, copper telluride can chemically react with acids or bases, which is also the basis for separating and recovering Cu and Te. In short, tellurium and copper combine with each other at a higher temperature to recover tellurium from the solution.
 

Specification of Telluride copper CuTe powder :

Black crystal powder, room temperature is stable in the air. Copper telluride is not only an important inorganic material, or stores a great form of tellurium and copper resources.

Product Performance of Mercury Telluride HgTe Powder :

The chemical formula of mercury telluride is HgTe, which is a binary inorganic compound composed of tellurium and mercury elements. It is a black crystal under room temperature.

Technical Parameter of Mercury Telluride HgTe Powder :

How is Mercury Telluride HgTe Powder Produced?
The preparation method of mercury selenide is as follows:
1. Under the condition of isolated air, dilute solution of HgCl2 is dropped into a saturated aqueous solution of H2Se to obtain HgTe precipitated product. Note that HgCl2 should not be in excess and a high concentration of HgCl2 solution should not be used, otherwise, HgCl2· 2HgTe precipitation will be formed.

2. Add HgCl2 to highly ammoniacal NaCN solution according to stoichiometric ratio, and then add equal weight SeO2.After the mixed solution is filtered, SO2 gas is passed into it. The solution must be kept alkaline throughout the reaction to prevent the red selenium from precipitating out. The endpoint of the reaction can be determined by the decrease in the rate at which SO2 is absorbed. At the end of the reaction, the black HgTe was filtered, washed with dilute NaCl solution containing ammonia, washed with distilled water, and finally dried in a dryer containing P2O5.

3. According to the stoichiometric ratio, Hg and Se are placed in a closed high-pressure vessel, and the reaction is carried out at the temperature of 550 ~ 600℃. Then the product is sublimated and purified in the pure N2 flow of 600 ~ 650℃, and pure HgTe can be obtained.
