  • Sulfur hexafluoride | F6S - PubChem

    Volatilization of sulfur hexafluoride from moist soil surfaces is expected to be an important fate process(SRC) given an experimental HenryLaw constant of 4.52 atm-cu m/mole(5). Sulfur hexafluoride is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 1.78X10+4 mm Hg(6).
