Sulfur Hexafluoride

Cylinder: 44L    Valve: DISS716    Content: 50kg

Sulphur hexafluoride is controlled under The Koto Protocol, an international Framework Convention with the objective of reducing greenhouse gases.

The chemical formula of sulfur hexafluoride is SF6, the molar mass is 7.1kg, and the density is 6.0886kg/m³.

Electronic grade high-purity sulfur hexafluoride is an ideal electronic etchant, widely used in the field of microelectronics.
Sulfur hexafluoride can also be used in the smelting and casting process of non-ferrous metals, as well as in the degassing and purification of aluminum and its alloy melts.
Mainly used for arc extinguishing in high-voltage switches, and used as insulating materials in large-capacity transformers and high-voltage cables.

Yes. Sulfur hexafluoride is a strong greenhouse gas, which has great harm to the earth's environment.

Sulfur hexafluoride is an odorless, non-toxic and non-flammable stable gas. Generally, it has special preservation methods, but if it leaks, it will react chemically with other substances and become harmful gases.

At present, the method of producing SF6 gas in the chemical industry is mainly formed by the direct reaction of elemental sulfur and excess gaseous fluorine; that is, S+3F2→SF6+Q (heat release). The synthesized SF6 gas also needs to go through a series of purification processes such as water washing, alkali washing, pyrolysis, drying, adsorption, freezing, distillation purification, etc. to obtain a product with a purity of more than 99.8%.
