• Sulphur Hexafluoride - SEMA Gases

    Sulfur hexafluoride (SF 6) is an inorganic, colorless, odorless, non-flammable, non-toxic but extremely potent greenhouse gas, and an excellent electrical insulator. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. Typical for a nonpolar gas, it is poorly soluble in water but quite soluble in nonpolar organic solvents.
