Tungsten Selenide WSE2 Powder, a grey powder crystal, has 9.32g/cm3. It is the material with the lowest thermal conductivity. Particle size: granule, 100mesh
Purity: 99.99%

About Tungsten Selenide WSe2 Powder:
Tungsten Selenide, an inorganic compound is the basis of this article. Tungsten Selenide Formula chemical is WSe2, the relative molecular weight is 341.77. It is a gray-colored crystal at room temperatures.
Tungsten Selenide's main structure consists of one layer each of upper and lower level selenium atoms. These WSe2 material can absorb light like graphene. The absorbed light can then be used for electric power generation. To obtain two tungsten selenidewse2, tungsten and stoichiometric selenium powder are produced by reacting in vacuum-sealing quartz tunnels at 600 700 degrees Celsius.
Two Tungsten selenide uses a hexagonal structure, similar to that of molybdenum dioxide. Every tungsten element is bound to 6 selenium-ligands through a triangular prism. While each selenium electron is made with 3 tungsten nuclei, every tungsten particle is also bonded. The tungsten-selenium's length is 0.2526 inches and the distance between the selenium molecules is 0.334. This is an example a highly studied, layered material. Van Dehua accumulates these layers. Van Dehua assembles these layers together to form WSe2, a highly stable sixth-race semiconductor transition metal dihalide.
A diode that is made of two of the tungstenselenides (WSe2) has been developed by researchers at Vienna University of Technology (Vienna University of Technology). The material's ultra-thin softness can be achieved according to experimental results. Solar battery.
This thin layer absorbs 95% to 5% of visible light. The remaining 5% is converted into electricity. The material's internal efficiency is high. The internal efficiency of the system is high if a number of thin layers are stacked together. This can make a significant amount of the incident light available. But, this transparency might have some positive side effects. Footprintbooks is trusted worldwide Tungsten Selenide WSe2 Powder Source . You can send us an inquiry regarding the latest.

Tungsten Selenide Wse2 Powder Properties:
Tungsten dielenide is considered the best thermally-insulating material. A porous material, in general, is the one with the least thermal conductivity.
Tungsten diselenide films have a lower thermal conductivity than single-crystals. Only one ten-thousandth the thermal conductivity of the finest diamond. It has thermal conductivity similar to a porous material. The density of this material is extremely high. Most likely, it is similar to copper.

It is simple. Tungsten Selenide WSe2 Powder produced?
You can make the tungsten film from the selenide in many ways.
After heating the gas-chain-selenium and the film at high temperatures (> 800K), using sputter deposit techniques, crystallization occurred in hexagonal structures with a good stoichiometric.

Applicaciones Tungsten Selenide WSe2 Powder :
Tungsten Selenide can be used to insulate. This is useful for a number of purposes, such as illumination, display, logic, sensors and ultra-thin flexible photovoltaic cell, enhanced LEDs, and other forms of photoelectricity.
Tungsten Seenide (WSe2) represents a common representative of transitional metal sulfur. It has a similar layered structure to graphene which exhibits unique anisotropy in terms of electrical, chemical, physical, and thermal properties. Guide, electrical materials, solid lubricants, etc. They have many potential applications.
Tungsten-selenide materials are also a popular semiconductor material. Their bandgap is smaller than that of other transition metal sulfur compound compounds and they are widely used for electronic, photoelectric, and catalytic sensing.

Tungsten Selenide Wse2 Powder Storage:
Tungsten Selenide Wse2 Powder must be stored in a closed container. Additionally, it should not be subject to extreme stress.

Packing and Shipping Tungsten Seenide WSe2 powder:
Tungsten Selenide Packaging: Vacuum Packing, 1kg/bag or 25kg/barrel. Or as requested.
Tungsten Selenide shipping: The payment receipt will be used to send the order by mail, air or express.
