• Byproducts of Sulfur Hexafluoride (sf 6) Use in the Electric

    Sulfur hexafluoride (SF 6) is a relatively nontoxic gas used in a number of applications for its inert qualities. The dielectric and other physical and chemical properties related to its lack of reactivity have led to the extensive use of SF 6 as an insulating medium in switching equipment (e.g., circuit breakers) by electric utilities. While SF 6
