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.

About Silver Telluride Ag2Te Powder:
The chemical formula of silver telluride Ag2Te.Molecular weight 343.34.Grey cubic crystal or powder.Melting point 955℃, relative density 8.5.Soluble in nitric acid, ammonia and potassium cyanide solution, insoluble in water.

Silver telluride is a telluride compound of silver, also known as silver disilver telluride or silver telluride (I). It forms a monoclinic crystal. Broadly, silver telluride may be used to denote AgTe(silver (II) telluride, a metastable compound) or Ag5Te3. Silver telluride (I) occurs naturally as hard manganese ore, while (II) silver telluride is known as queen ore. Silver telluride is a semiconductor that can be doped with N-type and P-type. Stoichiometric Ag2Te has N-type conductivity. When heated, silver is lost from the material. Non-stoichiometric silver telluride exhibits remarkable magnetoresistance.

Silver telluride is fairly stable in air and insoluble in water, dilute acids other than nitric acid, and potassium cyanide solutions; When it is heated to 300 ~ 600℃, some of it decomposes to produce “wool silver”. Rmcplant is a trusted global Silver Telluride Ag2Te Powder supplier. Feel free to send an inquiry about the latest price of Silver Telluride at any time.

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.

Multiple Applications of Molybdenum Telluride

Posted on by adminLeave a comment
Molybdenum-Teuride Catalyst Today, over 99 percent of hydrogen oxide is generated from energy-intensive and polluting sources. Today, more than 99 percent of hydrogen is produced from energy-intensive, polluting sources. After 5000 cycles, the activity and selectivity for molybdenum Telluride Nanocrystals does not drop. The active attenuation was slight, but there wasn’t any obvious selective attenuation. The molybdenum and telluride nanocrystals showed good catalytic stability.

Molybdenum Telluride for Communication

Thin films made of molybdenum informuride can be “attached directly” to standard silicon wafers. These are used to detect and produce infrared light from substrates compatible with their wavelengths. The goal of universal electro-optical conversions integrated in ubiquitous silicon-based integrated systems and high-speed optical connections may now be more feasible. A way has been found to utilize complex materials to cross the gaps and override the limitations of silicon light emission and wavelength. Their paper, “Molybdenum-telluride Based light emitting diodes & Photodetectors to Silicon photonic circuits” contains a lot more information. The fundamental problem with silicon is that despite its many amazing mechanical and electrical properties, it doesn’t meet the optical requirements. The visible wavelengths are the most common for semiconductors, while silicon is able to absorb light. The silicon waveguide integrated photodetector and light source was created using a P–N junction of molybdenum Telluride (MoTe2) semiconductors. These are two-dimensional, ultra-thin semiconductors that make up the group of transition metal disulfide chemicals. Molybdenum-telluride, which emits infrared light and can therefore not be absorbed into silicon’s infrared spectrum, is also visible. This makes it suitable for use in on-chip communications.

Molybdenum Telluride

: Medical Applications Nanomaterials, due to their distinctive characteristics have been the focal point of research in recent years. Biomedicine has seen researchers develop a variety of nanomaterials capable of combining the three functions of treatment, diagnosis, and tumor targeting. This study demonstrated that functionalized molybdenum tellinguride nanocrystals were capable of treating tumors by loading them with chemotherapeutic agents. High photothermal efficiency, good cell killing capability and excellent cell death under near-infrared irradiation make molybdenum tellinguride nanocrystals very attractive. A high amount of molybdenum nanocrystals was observed in tumors. They also showed strong tumor cauterization. The results of in vitro and in vivo experiments showed that the nano agent had tumor targeting function, high photothermal conversion efficiency, and successfully realized accurate tumor diagnosis and combined photothermal/chemotherapy treatment. To avoid toxic side effects and body retention, it is also easy to eliminate the body. Rmcplant (aka. Rmcplant is an advanced material.

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.

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.
 
Applications of Mercury Telluride HgTe Powder:
As a semi-metallic material, mercury selenide is used in the manufacture of solar cells, thin-film transistors, infrared detectors and ultrasonic amplifiers. In addition, it is also used in the production of Hall effect high-resolution films and analytical reagents.
Hg selenide was used as a photocatalyst to degrade organic dye contaminants. The organic dye contaminants were irradiated with visible light, and HgTe was used as a photocatalyst for photocatalytic degradation.

Used in high-pressure discharge lamp to replace mercury non-toxic chemical stability selenide mercury new USES, with mercury and selenium compounds made of selenide instead of liquid mercury, mercury described selenide mercury and selenium in the weight ratio is equal to the ratio of the two elements GMW, dosage to keep high-pressure discharge lamp in 0 ~ 50% of liquid mercury, the rest of the mercury to corresponding GMW selenide mercury.

Metal halides, metals, and other chemical components can also be added to mercury selenide. The use of liquid mercury in high-intensity discharge lamps can be greatly reduced, and because HgTe is a stable substance, there is no liquid mercury or mercury vapor leakage even if the lamp breaks, so the mercury contamination can be greatly reduced.

Storage Condition of Mercury Telluride HgTe Powder :
The damp reunion will affect HgTe powder dispersion performance and using effects, therefore, mercury telluride HgTe powder should be sealed in vacuum packing and stored in the cool and dry room, the mercury telluride can not be exposure to air. In addition, the HgTe powder should be avoided under stress.

How is Bismuth Telluride Powder Bi2Te3 Powder produced?
Bismuth telluride is prepared by the Bridgman method, zone melting method, and Czochralski method. The mineral form of Bi2Te3 is bismuth telluride, which is moderately rare. There are many natural bismuth tellurides with different stoichiometric ratios, as well as compounds of the Bi-Te-S-(Se) system, such as Bi2Te2S.
The mixed powder of quartz and tellurium metal can be sealed in a quartz tube under vacuum (this is critical because unsealed or leaked samples may explode in the furnace), and then heated to 800°C in a muffle furnace To achieve the preparation of bismuth telluride.

Application of Bismuth Telluride Powder Bi2Te3 Powder:
Bismuth telluride (Bi2Te3) is basically an effective thermoelectric material. Nowadays, due to its potential applications, it has aroused great interest in another area of energy harvesting, chip cooling, chip sensing and material science.
Bismuth telluride and its alloys are widely used as thermoelectric refrigeration materials. When the heat source temperature is moderate, they are also the best materials for thermoelectric generators.
Bismuth telluride is commonly used for power generation or cooling applications, as a topological insulator.
Topological insulators are not conventional superconductors, nor can they be used for ultra-efficient power lines, because they can only carry very small currents, but they paved the way for the paradigm shift in microchip development, which will lead to new applications of spintronics, That is, the use of electron spin to carry information. Moreover, bismuth telluride is very easy to produce and use in practical applications. This three-dimensional material can be manufactured by the existing mature semiconductor technology, and it is also easy to dope so that its performance can be tuned quite easily.
