How is Molybdenum Telluride MoTe2 Powder Produced?
Molybdenum can form a series of homogeneous compounds with sulfur, selenium and tellurium. Molybdenum disulfide (MoS2), molybdenum selenide (MoS2) and molybdenum ditelluride (MoTe2) are heterogeneous iso phase compounds. These compounds are usually formed by combining the corresponding elements directly at high temperatures in a sealed vacuum tube.
MoTe2(Motex x=1.88 ~ 2) and Mo3Te4 can be formed by the reaction of MoTe2 and Mo3Te4 within 15 minutes at 430℃.
Reactive: Mo+2Te → MoTe2
 
Applications of Molybdenum Telluride MoTe2 Powder:
Potential uses of MoTe2 are lubricants, electronics, optoelectronics or photocell materials.

Make transistors with MoTe2.MoTe2 has the potential to manufacture low-power electronic products. Field-effect transistors (FETs) are made up of two, three, and thicker nanolayers. A bipolar field-effect transistor has been built, as well as a field-effect transistor that can operate in either N or P mode, with two top electrodes.

Because MoTe2 has two phases, it is possible to construct a device in the form of a 2H semiconductor and 1T’ metal.

The MOSFET can consist of a thin layer of MoTe2 covered by a gate consisting of an ionic liquid or a liquid electrolyte such as potassium perchlorate dissolved in polyethylene glycol. When the gate voltage is below 2 volts, the device operates in electrostatic mode, and the current from drain to source is proportional to the gate voltage. Beyond 2 volts, the device enters an intermediate region where the current does not increase. A current of more than 3.5 volts leaks through the gate and electrolysis occurs when potassium atoms are inserted into the MoTe2 layer. Potassium intercalated molybdenum ditelluride is superconducting below 2.8 K.

As a lubricant, molybdenum ditelluride works well in a vacuum at temperatures up to 500 ° C with a coefficient of friction below 0.1. However, molybdenum disulfide has less friction, whereas molybdenum diselenide can function at higher temperatures.

Molybdenum ditelluride can form at the contact point, and if this is n-type, then small pieces of the molybdenum ditelluride nano-layer can be mixed or dispersed in the molten tin without reacting, which doubles the stiffness of the composite.

Molybdenum ditelluride has been examined for protein substrates by atomic force microscopy. It is superior because proteins stick harder than traditional materials such as mica.

Storage Condition of Molybdenum Telluride MoTe2 Powder :
The damp reunion will affect MoTe2 powder dispersion performance and using effects, therefore, molybdenum telluride MoTe2 powder should be sealed in vacuum packing and stored in cool and dry room, molybdenum telluride can not be exposure to air. In addition, the MoTe2 powder should be avoided under stress.

Packing & Shipping of Molybdenum Telluride MoTe2 Powder :
We have many different kinds of packing which depend on the molybdenum telluride MoTe2 powder quantity.
Molybdenum telluride MoTe2 powder packing: vacuum packing, 100g, 500g or 1kg/bag, 25kg/barrel, or as your request.

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. Tqhp is a trusted global Tungsten Telluride WTe2 Powder supplier. Feel free to send an inquiry about the latest price of Tungsten Telluride at any time.

Product Performance of Tungsten Telluride WTe2 Powder :

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.

Product Performance of Cadmium Telluride CdTe Powder :

Cadmium telluride is a crystalline compound formed from cadmium and tellurium. It is sandwiched with calcium sulfide to form a p-n junction photovoltaic solar cell. It has very low solubility in water and is etched by many acids such as hydrobromic and hydrochloric acids. It is commercially available as powder or crystals.

How is Cadmium Telluride Powder CdTe Powder produced?
The mixture of tellurium and cadmium is melted and sublimated in a hydrogen stream, or cadmium tellurite or tellurite is heated and reduced in a hydrogen stream. It can also be reacted by sodium telluride and a cadmium acetate solution acidified by acetic acid. It is brownish-red when precipitated, and almost black after drying. It can also be obtained by acting on cadmium vapor with hydrogen telluride to form a single crystal of cadmium telluride. Using high-purity tellurium and cadmium as raw materials, cadmium telluride is synthesized after deoxidation and then grown into a single crystal or polycrystalline by vertical crystallization method or vertical zone melting method.
 
Application of Cadmium Telluride Powder CdTe Powder:
CdTe is mainly used in solar cells, thermoelectric conversion elements, refrigeration components, thermal, photosensitive, piezoelectric crystals, nuclear radiation detection and infrared detectors. It can also be used in industrial additives such as semiconductor devices, alloys, chemical raw materials and cast iron, rubber, Glass, etc.
CdTe is used to make thin-film solar cells.
CdTe can be alloyed with mercury to make a universal infrared detector material (HgCdTe).
CdTe can be an excellent solid-state X-ray and gamma-ray detector (CdZnTe), where CdTe is alloyed with a small amount of zinc.
CdTe is used as an infrared optical material for optical windows and lenses and has been proven to have good performance in a wide temperature range.
CdTe is also used in electro-optic modulators. Among the II-VI compound crystals, it has the largest electro-optic coefficient in the linear electro-optic effect (r41 = r52 = r63 = 6.8×10-12 m / V).
CdTe doped with chlorine is used as a radiation detector for X-rays, gamma rays, beta particles and alpha particles.
CdTe can operate at room temperature, so a compact detector can be constructed for various applications in nuclear spectroscopy.
CdTe outstanding performance in realizing high-performance gamma-ray and X-ray detectors is its high atomic number, high charge collection and excellent spectral resolution

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”. Tqhp is a trusted global Silver Telluride Ag2Te Powder supplier.

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.

Storage Condition of Silver Telluride Ag2Te 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.
 
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.
