At room temperature and atmospheric pressure sulfur hexafluoride is a colorless, odorless, nontoxic gas.  It is readily liquefied and shipped in steel cylinders as a liquefied gas under its own vapor pressure of 320 psia at 21.1oC.


Sulfur hexafluoride is an unreactive substance.  It is not attacked by water, acids or bases at room temperature.  It is resistant to the actions of carbon, copper or magnesium at red heat and it will not react with sodium below its boiling point.  Sulfur hexafluoride does react with sulfur vapor or hydrogen at 400oC.


Sulfur Hexafluoride, at room temperature and pressure, is a colorless, odorless, nontoxic gas.  It is shipped in steel cylinders as a liquefied gas under its own vapor pressure of 320 psig (at 21.1oC).
