Sulfur Hexafluoride (gaz sf6) | Encyclopedia.com

IntroductionHistorical Background and Scientific FoundationsImpacts and IssuesBibliographySulfur hexafluoride (chemical formula gaz sf6) is a compound of sulfur and fluorine and the most potent greenhouse gas known. Several classes of compounds containing fluorine—including the chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), hydro-fluorocarbons (HFCs), perfluorocarbons (PFCs), and sf 6—are potent greenhouse gases. HCFCs and CFCs are better-known as destroyers of atmospheric ozone, and are regulated under the 1987 Montreal Protocol that has been widely hailed as successful at halting depletion of the ozone layer. Although Sulfr hexafluoride is a potent greenhouse gas and its concentration in the atmosphere is increasing rapidly, its contribution to global warming is much smaller than that of the major greenhouse gases, especially carbon dioxide and methane, because it is present in smaller quantities. gaz sf6 is one of the six greenhouse gases regulated under the Kyoto Protocol.Get price
