Chemical formula: SF₆Melting point: −64 &C; −83 &F; 209 KMolar mass: 146.06 g/molSolubility in water: 0.003% (25 &C)OverviewSulfur hexafluoride (SF6) or sulphur hexafluoride (British spelling), is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non flammable, and non toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of 6.12 g/L at sea level conditions, considerably higher than the density of air (1.225 g/L). It is generally transported as a liquefied compressed gas. The concentration of SF 6 in Earth's troposphere reached 10 parts per trillion (ppt) in year 2019, rising at 0.35 ppt/year. The increase over the prior 40 years was driven in large part by the expanding electric power sector, including fugitive emissions from banks of SF 6 gas contained in its medium and high voltage switchgear. Uses in magnesium, aluminum, and electronics manufacturing also hastened atmospheric growth.

2020/4/19Insulation effectiveness is measured by its thermal resistance value, or R value, a number between 1 and 60 that reflects the material's resistance to heat transfer. The better the insulation, the higher the R value. This number is determined by the type of insulation, its thickness, density, and where and how the insulation is installed.

Reviews: 18Estimated Reading Time: 9 minsPublished: 2014/11/10 Where is SF6 used? The following applications are known. For some of these most probably you haven't heard of. For sound insulation in windows, In vehicle tyres,Is SF6 a health hazard? Pure SF6 is physiologically completely harmless for humans and animals. It's even used in medical diagnostic. Due to its weight it might displace the oxygen in the air, if large quantities are concentrating in deeper and non ventilated places.Is SF6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse effect, if it is released into the atmosphere.What is the overall contribution of SF6 used in the electrical equipment to the greenhouse effect? Less than 0,1 % ( see CAPIEL) and CIGRE). In an Ecofys study the contribution to the greenhouse effect in Europe is estimated to 0.05 % (*).See full list on electrical engineering portal(PDF) Fluoronitriles/CO2 gas mixture as promising substitute to SF6 for insulation in high voltage applications researchgate.net/publication/310466698_Fluoronitriles...PDF | This paper is aimed at the breakdown characteristics of Fluoronitriles – CO2 gas mixtures in different experimental conditions; these mixtures... | Find, read and cite all the research you
