IntroductionProperties of SF6ExperimentalResultsDiscussion and ConclusionsAcknowledgmentsSF6 is a stable, inert, inorganic, colorless, odorless, non polar and non toxic gas with a boiling point of −64&C (−58&F) at 100 Pa (1, 11). SF6 has a vapor pressure of 290 Pa at 21.1&C and a molecular weight of 146.055 g/mol. Compounds with this molecular weight generally exist as liquids. However, the strong bonds between the sulfur and the fluorine atoms create weak intermolecular London dispersion forces, which translate to a low liquefaction temperature thus allowing it to exist as a gas at room temperature …See more on academic.oupCited by: 8Publish Year: 2015Author: Edmund C Jong, Paul V Macek, Inoka E Perera, Kray D Luxbacher, Harold M McNairEstimated Reading Time: 11 minsDetection of Trace Disulfur Decafluoride in Sulfur Hexafluoride by … tsapps.nist.gov/publication/get_pdf.cfm?pub_id=13110PDF fileby Gas Chromatography/Mass Spectrometry James K.
