The decomposition products of sulfur hexafluoride (insulating gas

Nov 01, 2007 · It is almost insoluble in water but soluble in a variety of organic solvents (e.g. acetone). It can be catalytically decomposed in the presence of water, S 2 F 10 + H 2 O → 2HF + SOF 2 + SF 6. The compound is stable to acid, is hydrolyzed by water and alkalies, and at 200 °C in the presence of copper or mercury almost decomposes to SF 4 and SF 6.Get price

The decomposition products of sulfur hexafluoride (insulating gas

Decomposition of sf 6 in an RF Plasma Environment

Sulfr hexafluoride clearly increased from 37.79 to 95.68% because of an increase in power from 5 to 20 W. When the power exceeded 40 W, η Sulfr hexafluoride exceeded 99%. When oxygen was introduced into the reactor (feed O 2 /SF 6 ratio = 2.0), η Sulfr hexafluoride was ~10% less than when no oxygen was added (from 28.61 to 86.09% as the power rose from 5 to 20 W).

Decomposition Characteristics of insulating gas under Flashover

Derdouri et al. [ 12] designed a study on the SF 6 decomposition products when water vapor exists and found that SOF 2 and SO 2 F 2 generate stably in existence of water vapor.

Measurement of Water Vapor in Sulphur Hexafluoride, Sulfr hexafluoride

Water Vapor in gaz sf6 Since Sulfr hexafluoride itself is chemically inert, it can not and does not cause corrosion. However, in the presence of water vapor, H2O, primary and secondary decomposition products hamper natural recombination of the sf6 gas. These decomposition products form the highly corrosive electrolyte hydrogen fluoride (HF).Get price
