Tungsten Hexafluoride 99.999% purity WF6 Industrial Gas

It is an inorganic compound with the chemical formula WF6. It is a colorless gas at normal temperature and pressure, soluble in most organic solvents.

As an electronic grade material, tungsten hexafluoride plays an important role in the semiconductor manufacturing process. Its main use is as a raw material in the chemical vapor deposition (CVD) process, which can help form high-purity semiconductor materials and improve the performance and stability of semiconductor devices. As a polar material, tungsten hexafluoride can be used in the manufacture of liquid crystal display. In the liquid crystal manufacturing process, tungsten hexafluoride is mainly used as a polar group in polar molecules, which can improve the response ability and display effect of liquid crystal displays to external light. Tungsten hexafluoride can be used as an electronic-grade material in the manufacturing process of solar cells. In solar cells, tungsten hexafluoride is mainly used for the preparation of electron transport layers, which can improve the absorption capacity of solar cells and photoelectric conversion efficiency.
