General Properties of Sulfur HexafluorideUses of Sulfur HexafluorideMajor Application AreasIt is a colourless, odourless, tasteless, non combustible gas. It is liquefied under its vapour pressure when sent to another location. Contact with the gas may lead to frostbite. While exposed to fire or heat for an extended period, there's a possibility of rupturing the container with great sound. The estimated lifetime of SF6is in the range of 800 3200 years. 1. Atomic Structure (Image to be added soon) This picture depicts the structure of sulfur hexafluoride. 1.
