About Tungsten Selenide WSe2 Powder:
Tungsten salenide, an organic compound, is Tungsten Chemical formula HTML2_ is WSe2. The relative molecular Mass of Tungsten Selenide HTML2_ is 341.77. At room temperature, it is a gray-colored crystal.
Tungsten Selenide has one layer of Tungsten in its main structure. It is composed of one layer of Tungsten. Such WSe2 materials absorb light, such as from graphene. Electric power can also be generated by the absorption of this light. At 600 700° C, Tungsten and stoichiometric orelenium powder react with vacuum sealing quartz tunnels to create two tungsten selendewse2.
Two Tungsten Salenide utilizes a hexagonal, crystal-like structure. Every tungsten is attached to six selenium molecules in a triangular prism. The selenium is then shaped by three tungsten acid bonds. This is one example of an adequately studied layer material. Van Dehua is responsible for accumulating these layers. Van Dehua creates the layers.
Researchers at the Vienna University of Technology developed a diode from two tungstenselendes (WSe2) by their team. It can also be used to create ultra-thin, soft materials according to laboratory experiments. Solar battery.
This thin layer is lightweight and thin. It reflects 95%, while the other 5% of light will be absorbed. Because of this, it has an excellent internal efficiency. An extremely high internal efficiency can be achieved if multiple thin layers are placed next to each other. Please feel free to contact us for information about the Tungsten Selenide.
Tungsten selenide WSe2 powder:
Tungsten dielenide is the highest thermally insulating substance found. In general, the material that has the lowest thermal conductivity (or the greatest thermal insulator) are porous materials.
Films of tungsten dielenide tungsten is less thermal conductive than single crystal tungsten. Very likely, only one-tenthth of the diamond has the highest thermal conductivity. The material does not have the thermal conductivity of a porous matter, but has it. More important, the density is high. Most likely, it is similar to that of copper.

How is Tungsten Selenide WSe2 Powder produced?
There are many methods to make the tungsten-containing selenide film, the most common being chemical or physical.
The film was heated with the gas-chain selenium and then deposited at high temperatures (> 800K) using the sputtering techniques. It crystallized in a hexagonal form that had a good stoichiometric balance.
W + 2Se → WSe2

Tungsten-selenide powder can serve as an insulation material, optimizing efficiency and spectral characteristics in different applications such as illumination and display.
Tungsten selenide (WSe2) can be a good example of transition metal sulfur. With a structure similar to graphene’s, it exhibits strong anisotropy for electrical, chemical or mechanical properties. Guide, electrical materials, solid lubricants, etc. have wide application possibilities.
Tungsten Selenide materials also serve as typical semiconductor materials. Tungsten Selenite compounds have a smaller range of bandgaps than transition metals sulfur chemicals, making them more common in electronic sensing and photoelectric catalytic experiments.
Storage Condition of Tungsten Selenide WSe2 Powder:
Tungsten Selenide, WSe2 powder should be packed in a vacuum. Also, avoid stress.
