Sulfur hexafluoride (SF 6) is an inorganic, colorless, odorless, non-flammable, extremely potent greenhouse gas which is an excellent electrical insulator. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. SF 6 plasma is also used in the semiconductor industry as an etchant. 2  SF 6 breaks down in the plasma into sulfur and fluorine, the fluorine plasma performing the etching. 3  The magnesium industry uses large amounts of SF 6 as inert gas to fill casting forms. 4  Pressurizes waveguides in high-power microwave systems.
