About Tungsten Selenide WSe2 Powder:
Tungsten Selenide (also known as Tungsten Selenide) is a compound that is inorganic. Tungsten Selenide Chemical Formula It is WSe2, with a relative molecular Mass of 341,77. At room temperature, it is a grayish crystal.
Tungsten Selenide has a main structure that is made up of tungsten atoms in the middle of upper and lower selenium. The WSe2 material can absorb rays, like graphene. This absorbed light is then used to generate electricity. The reaction of tungsten powder and stoichiometric selenium powder in quartz vacuum tunnels at 600-700 deg C produces two tungsten selenidewse2.
Two Tungsten Selenide uses a hexagonal crystalline structure similar to molybdenum sulfide. Each tungsten-selenium ligand is formed by 3 tungsten-atomic bonds. The distance between selenium molecules is 0.334 nanometers, while the length of tungsten and selenium is 0.2526 nanometers. This is an example layered material which has been thoroughly studied. Van Dehua combines these layers. WSe2 has a high stability for a transition metal dihalide.
The researchers at Vienna University of Technology developed a diode that is made of two tungsten selenides. According to the experiments, this material could be used to create ultra-thin softness. Solar battery.
This thin layer has a light weight and is thin. It absorbs 95% of light. The remaining 5% will be converted to electricity by the material. The internal efficiency of the material is very high. A plurality of ultra thin layers can be stacked together to use a large portion of the incident light. But sometimes, this high transparency has beneficial side effects. is a trusted, global Tungsten Selenide WSe2 Powder You can also contact us by clicking here. .

Tungsten Selenide powder:
Tungsten Diselenide, the most thermally-insulating material so far found. In general the material with the lowest thermal conductivity is called a porous material.
Thermal conductivity is less for tungsten dielenide films than it is for tungsten monocrystals. It is estimated that the thermal conductivity of the diamond, which has the best thermal properties, is only about one tenth. This new material is not just porous but also has thermal conductivity. The density of this material is extremely high. Like copper.

What is Tungsten Selenide WSe2 Powder produced?
There are several ways to make the tungsten-selenide film, mainly using the chemical and physical laws.
The film was heated by sputtering at high temperatures (>800K) from the gas-chain of selenium, resulting in the formation of a hexagonal crystal structure with the correct stoichiometric formula.
W + 2Se
