Cadmium Telluride Powder CdTe Cas 1306-25-8

About Cadmium Telluride Powder CdTe Powder:
The chemical formula of cadmium telluride is CdTe, the molecular weight is 240.00, and it has certain liver and kidney toxicity. The melting point is 1041℃, and it decomposes when the temperature is higher, and the relative density is 6.2015. It is insoluble in water and acid but can be decomposed by reacting with nitric acid. It is easily oxidized by air when wet.
Cadmium telluride (CdTe) is a stable crystalline compound formed from cadmium and tellurium. It is mainly used as a semiconductor material and infrared optical window in cadmium telluride photovoltaic cells. It is usually sandwiched with cadmium sulfide to form a p-n junction solar photovoltaic cell. Generally, CdTe PV cells use an n-i-p structure.
Bulk CdTe is transparent in the infrared, from close to its bandgap energy (1.5 eV at 300 K, corresponding to an infrared wavelength of about 830 nm) to wavelengths greater than 20 µm. Correspondingly, CdTe fluoresces at 790 nm. As the size of CdTe crystals is reduced to a few nanometers or less, so that they become CdTe quantum dots, the fluorescence peaks move to ultraviolet light in the visible light range.
CdTe is insoluble in water. CdTe has a high melting point of 1041°C and evaporates from 1050°C. The vapor pressure of CdTe at ambient temperature is zero. Due to its high melting point and insolubility, CdTe is more stable than its parent compounds cadmium and tellurium and most other Cd compounds. Feel free to send an inquiry to get the latest price if you would like to buy Cadmium Telluride Powder CdTe in bulk.

Silver TellurideAg2Te99.99%-100 mesh343.348.5 g/cm3Gray Black

 

How is Silver Telluride Ag2Te Powder Produced?
Silver telluride process: Produced by the interaction of silver with tellurium at high temperatures (to volatilize excess tellurium) and in a flow of hydrogen gas.

Silver telluride is obtained by heating silver and tellurium together in a vacuum container until reddish. Or from the reaction of tellurium with a hot solution of silver nitrate. In addition, the H₂ TE and soluble silver salt solution reaction can also make silver telluride.
 
Applications of Silver Telluride Ag2Te Powder:
The utility model relates to a vertical-cavity surface-emitting laser containing silver telluride/silver zinc telluride core-shell quantum dots and a preparation method thereof. The vertical cavity surface emitting laser comprises a quartz substrate arranged upward in sequence, a lower high mirror, a silica layer containing silver telluride/silver zinc telluride core-shell quantum dots and an upper high mirror.

Single crystal Ag2Te nanowires with uniform dispersion were synthesized. A series of X-ray diffraction (XRD) and scanning electron microscopy (SEM) characterization showed that the Ag2Te sample has a controllable morphology, good crystallinity and high purity nanostructure, the diameter of which is about 200nm, the length of which can reach tens of microns. More importantly, the associated electrical properties of a single Ag2Te nanowire. It is found that the I-V curves of the samples are symmetric and non-linear at room temperature by in-situ electric field assembly and voltammetry measurement. During the heating process, the I-T curve is accompanied by the phase transition, and the current also changes greatly. These experimental results lay a good foundation for further research on the electrical transport performance of nanostructured devices in the future.

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.

Mercury TellurideHgTe99.99%-100 mesh328.1912068-90-5Gray Black

 

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.
