Feel free to send an inquiry about the latest price of Molybdenum Telluride at any time.
Product Performance of Molybdenum Telluride MoTe2 Powder :
MoTe2 is a gray hexagonal powdery solid with various morphologies. Among them, MoTe2 and Mo3Te4 are stable in air and decompose in alkali. It is insoluble in water, soluble in nitric acid, and can decompose (not melt) at high temperatures in a vacuum.
Technical Parameter of Molybdenum Telluride MoTe2 Powder :
Product Name | MF | Purity | Particle Size | Molecular Weight | CAS | Color |
MolybdenumTelluride | MoTe2 | 99.99% | -100 mesh | 351.14 | 12058-20-7 | Gray Black |
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.

About Silicon Dioxide SiO2 powder:
Silica, also known as silicon dioxide, is a silicon oxide with the chemical formula SiO2. The most common form in nature is quartz and various organisms. In many parts of the world, silica is the main component of sand. Silica is one of the most complex and abundant material families, in the form of mixtures of various minerals and synthetic products. Notable examples include fused silica, fumed silica, silica gel and aerogel. It is used in structural materials, microelectronics (as electrical insulators), and components in the food and pharmaceutical industries.
Inhalation of finely divided crystalline silica is toxic and can cause severe inflammation of lung tissue, silicosis, bronchitis, lung cancer and systemic autoimmune diseases such as lupus and rheumatoid arthritis. High-dose inhalation of amorphous silica can cause non-permanent short-term inflammation, and all effects can be cured.
Long-range arrangement of silicon and oxygen atoms forms crystalline silica, short-range arrangement or long-range disordered arrangement forms amorphous silica. In a silicon dioxide crystal, the silicon atoms are at the center of a regular tetrahedron, and the four oxygen atoms are at the four corners of the tetrahedron. Many tetrahedrons are held together by oxygen atoms at the four corners. Each oxygen atom is shared by two tetrahedrons, that is, each oxygen atom is bonded to two silicon atoms.
The simplest molecular formula for silica is SiO2, but SiO2 does not represent a simple molecule (just the ratio of the number of silicon atoms to the number of oxygen atoms in the crystal of silica). Pure natural silica crystal is a hard, fragile, insoluble, colorless and transparent solid, often used in the manufacture of optical instruments. Feel free to send an inquiry to get the latest price if you would like to buy Silicon Dioxide SiO2 powder in bulk.
Performance of Silicon Dioxide SiO2 powder :

How is Silicon Dioxide SiO2 powder produced?
Preparation method of amorphous silicon dioxide
The preparation of amorphous silica includes five steps, namely the preparation of silica gel, granulation process, sintering process, cleaning process and drying process.
1. Preparation of silica gel
Crushing silicon tetrachloride can produce silica gel, or pulverizing organic silicon compounds (such as tetra methoxy siloxane) to produce silica gel, or using fumed silica can produce high-quality silica gel.
2. Granulation process
By drying the silicone gel into a dry powder, pulverizing the dry powder, and then performing classification, a silica powder with a desired average yield can be obtained.
3. Sintering process
The silica powder obtained in the granulation process is sintered at a temperature of 800°C to 1450°C. The spheroidization process of thermal plasma is used to introduce argon gas at a predetermined flow rate and convert the output at a predetermined frequency to generate plasma. In the plasma torch, the sintered and obtained silica powder is dispersed at a predetermined feed rate, and heated and melted at a temperature of 2000 ℃ to the boiling point of silica.
4. Cleaning process
After the spheroidization step, the fine powder adhering to the surface of the spheroidized silica powder is removed.
5. Drying process
After the above cleaning process, the silica powder is dried.
Applications of Silicon Dioxide SiO2 powder:
Silica is a raw material for manufacturing glass, quartz glass, water glass, optical fiber, important parts of the electronics industry, optical instruments, handicrafts and refractory materials, and important material for scientific research.
1. Silica is the main ingredient in most glass production. When other minerals melt with silica, the freezing point reduction principle reduces the melting point of the mixture and increases the fluidity. The glass transition temperature of pure SiO 2 is about 1475K. When fused silica SiO2 cools quickly, it will not crystallize but will solidify into the glass. Therefore, most ceramic glazes are mainly composed of silica.
2. Silica can also be used as an additive, an excellent flow promoter, mainly used as a pressurizing agent, anti-sticking agent, and glidant.
3. Silica is particularly suitable for the granulation of oils and extracts, and it can also use glidants in direct compression.
4. As a disintegrant, silicon dioxide can greatly improve the fluidity of the granules, increase the bulk density, and increase the hardness of the prepared tablets. It can be used as an internal desiccant in the manufacture of granules to enhance the stability of the drug.
5. Silica can also be used as a filter aid, scavenger, defoamer, suspending agent and thickener for liquid preparations.
6. About 95% of the commercial uses of silica (sand) occur in the construction industry, such as the production of concrete (Portland cement concrete).
7. In cosmetics, silica plays a certain role due to its light diffusion properties and natural absorption.
8. The process of passivating the silicon surface by thermal oxidation (silicon dioxide) is critical to the semiconductor industry. It is usually used to manufacture metal oxide semiconductor field-effect transistors (MOSFET) and silicon integrated circuit chips (using planar technology).
9. Silica can be used for the extraction of DNA and RNA because it can bind to nucleic acids in the presence of chaotropic agents.
10. Since silicon dioxide is a natural oxide of silicon, compared with other semiconductors such as gallium arsenide or indium phosphide, silicon dioxide is more widely used.
11. Silicon dioxide can be grown on the surface of silicon semiconductors. The silicon oxide layer can protect the silicon surface during the diffusion process and can be used as a diffusion mask.
