Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride, 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 ofGet price

Sulfr hexafluoride Transmitter - Draeger

Increased safety, cost reduction and climate protection. When insulating switchgear or transformers, sulfur hexafluoride (sf6 gas) is used. Since it is technically almost impossible to hermetically seal these systems, emissions can escape into the environment. Gas detection systems from Dräger make it possible to detect even the smallest leaks at an early stage and initiate corrective measures.Get price

Jim Conway - Ireland | Professional Profile | LinkedIn

We investigated the variation of atomic oxygen density for various mixtures of O2/gaz sf6 and report a significant five-fold increase of [O] when oxygen plasma was diluted with Sulfr hexafluoride by only 5%. We attribute this increase in [O] to a combination of a change in surface conditions caused by constituents of gaz sf6 plasma reacting with the reactor walls andGet price

The dissociation fraction in Sulfr hexafluoride/Ar (95/5%) plasma at 20 mTorr was over a factor of 22 lower than Sulfr hexafluoride/O2/Ar (85/10/5%) plasma. For a fixed gas pressure and power of 60 mTorr and 500 W the F+ signal showed a variation of up to a factor of 60 depending if O2 was in the feedstock gas which indicates a marked enhancement of [F] with O2 addition.Get price

Precision plasma etching of Si, Ge, and Ge:P by Sulfr hexafluoride with added O2

Mar 31, 2014 · The impact of the O 2 content in SF 6 -O 2 gas mixtures on the etch rate and sidewall profile of silicon (Si), germanium (Ge), and phosphorous doped germanium (Ge:P) in reactive ion etching has been studied. The characteristics of etch rate and sidewall profile are greatly affected by the O 2 content. Below 50% of O 2 content, a large variation in Ge etch rates is found compared to that of Si, but for O 2 content above 50% the etch rates follow relatively the same trend.Get price
