  • Semiconductors

    Sulphur hexafluoride is used as a plasma etching gas.

  • Glass

    Sulphur hexafluoride is often used as a filling gas in double glazing as it reduces the sound transmissions and the heat transfer.

  • Metal Treating
    Metal Treating

    As sulphur hexafluoride is both inert and considerably denser than air it is suitable for blanketing open baths of certain molten metals, particularly magnesium.

  • Scientific Experiments
    Scientific Experiments

    Sulphur hexafluoride is used in laboratories as a carrier gas media in supercritical fluid chromatography (SFC), and as media in supercritical fluid extraction (SFE) for sample preparation.

  • Medical

    Sulphur hexafluoride is being used for medical purposes such as a contrasting agent for ultrasound examinations, and in retinal surgery.

  • Tyres

    Sulphur hexafluoride is also used as tyre filling gas.

Frequently Asked Question
  • Q: What’s the specification can you supply?

    Cylinder: 44L    Valve: DISS716    Content: 50kg

  • Q: Is sulfur hexafluoride a greenhouse gas?

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

  • What is the formula for sulfur hexafluoride?

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

  • What are the uses of sulfur hexafluoride?

    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.

  • Is sf6 a greenhouse gas?

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

  • Is sulfur hexafluoride safe?

    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.

  • How to get sulfur hexafluoride?

    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%.
