sf6 gas Decomposition in Gas-Insulated Equipment - IEEE Journals

Abstract: The increasing application of Sulfr hexafluoride as an insulating gas has led to many studies on Sulfr hexafluoride 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 gaz sf6.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 insulating gas. The decomposition fraction of Sulfr hexafluoride [etasf 6 (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/sf 6 ratio in an SiO2 reactor.Get price
