The decomposition products of sulfur hexafluoride (SF6): Reviews of environmental and health risk analysis

Separation of SF6 from SF6/N2 mixture using metal–organic framework MIL-100(Fe) granule

“…Sulfur hexafluoride (SF 6 ) has been widely used as an insulating and etching gas in the electric industry due to its chemical stability, non-toxicity, non-combustibility, and good insulating characteristics [1,2]; however, SF 6 is a very potent greenhouse gas since its global warming potential (GWP) is 23,900 times higher than CO 2 , and its lifetime is estimated to be 3200 years in the atmosphere [3]. Therefore, efficient methods for the recovery or the decomposition of this gas should be developed because of its long-term effect on the environment [4][5][6].…”

Surfactant effects on SF6 hydrate formation

“…It should be noted that the use of SF 6 gas increases especially in many developing countries. However, the chemically stable gas is one of the most potent greenhouse gases (GHGs) that cause significantly global warming, and has been, thus, blanketed into the Kyoto Protocol [1]. The global warming potential of SF 6 is 23,900 times larger than CO 2 and it remains in the air for 3200 years (CO 2 , CFCs: 100 years/CH 4 : 10 years).…”

Corrosivity of HFC125 as Shielding Gas for Magnesium Melt under High Temperature

“…H 2 O, N 2 , O 2 ), the decomposition products of HFC125 at evaluated temperature may include HF, COF 2 , CF 3 CF, CF 2 CF 2 , CHF 3 , CF 2 , CHF 2 and CF; [2][3][4] those of SF 6 may include S 2 OF 10 , SO 2 , S 2 F 10 , SF 4 , SO 2 F 2 , SOF 2 , SOF 4 , F 2 , S 2 O 2 F 10 , H 2 S, HF and F 2 O. 4,5) HFC125 and SF 6 become corrosive at high temperature because most of these thermal decomposition products are corrosive.…”
