sf 6 Decomposition Reclamation

insulating gas Decomposition Reclamation Abstract: The increasing application of gaz sf6 as an insulating gas has led to many studies on insulating gas decomposition in gas-insulated equipment. In the presence-of an electric arc, spark or corona, Sulfr hexafluoride decomposes to a wide variety of chemically active products which possess completely different properties from sf6 gas.Get price

Study of arc development mechanisms over solid insulators

Sep 23, 2020 · One of the suggested solutions is the fluoronitrile (C4F7N), a gas having alone a dielectric withstand 2.7 times higher than Sulfr hexafluoride. However, its high liquefaction temperature requires to dilute it for use, mixed with CO2. O2 can also be added to address issues regarding the gas mixture decomposition during arc interruption.Get price


gaz sf6 is also heavily used to clean chamber walls from organic polymer deposition coming from etch processes: waferless autoclean (WAC). It consists of 2 steps: the 1st one, based on Sulfr hexafluoride O2, allows to remove Si and C residues, while in the 2nd one high O2 flow removes all the F compounds.Get price
