Sulfur hexafluoride - Wikipedia

6, a process termed "self-healing". Arcing or corona can produce disulfur decafluoride (S 2 F 10), a highly toxic gas, with toxicity similar to phosgene. S 2 F 10 was considered a potential chemical warfare agent in World War II because it does not produce lacrimation or skin irritation, thus providing little warning of exposure. SFGet price

Decomposition of sf6 gas and H2S Mixture in Radio Frequency

May 28, 2003 · Sulfur hexafluoride (sf 6) is a gaseous pollutant generated in manufacturing processes in the semiconductor industry. Hydrogen sulfide (H2S), as a reductant, was used to treat gaz sf6 in a radio frequency (RF) plasma system. In the sf 6/Ar plasma system, SiF4 and SO2 were the two dominant species detected in the glass reactor; other detected species were SO2F2, SOF2, and SOF4. In the sf6 gas/H2S/ArGet price

Sulfr hexafluoride Transmitter - Draeger

The infrared sensor measures insulating gas in the ppm range so the transmitter can detect a leak in time. It also makes it easier for you to comply with occupational exposure limits. Connect the Sulfr hexafluoride transmitter via an analogue or digital interface with a Dräger control unit to a gas warning system. This warns you early on exceeding the preset alarm values.Get price

Decomposition of insulating gas in an RF plasma environment.

Sulfur hexafluoride (SFd)-contained gas is a common pollutant emitted during the etching process used in the semiconductor industry. This study demonstrated the application of radio-frequency (RF) plasma in the decomposition of sf 6. The decomposition fraction of Sulfr hexafluoride [etainsulating gas (C (in)-C (out))/C (in) x 100%] and the mole fraction profile of the products were investigated as functions of input power and feed O2/sf6 gas ratio in an SiO2 reactor.Get price
