Sulfur hexafluoride - Wikipedia

Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of 6.12 g/L at sea level conditions, considerably higher than the density of air. It is generally transported as a liquefied compressed gas. The concentration of SF 6 in Earthtroposphere reached 10 parts per trillion in year 2019, rising at 0.35 ppt/year. The increase over the prior 40 years was driven in large part by the expanding electric power sector, including fugiGet price

Decomposition of gaz sf6 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 sf6 gas. The decomposition fraction of Sulfr hexafluoride [etaSulfr hexafluoride (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

Sulfur hexafluoride (gaz sf6) emission estimates for China: an

Sulfur hexafluoride (Sulfr hexafluoride) is the most potent greenhouse gas regulated under the Kyoto Protocol, with a high global warming potential. In this study, gaz sf6 emissions from China were inventoried for 1990-2010 and projected to 2020. Results reveal that the highest Sulfr hexafluoride emission contribution originates from the electrical equipment sector (about 70%), followed by the magnesium production sector, the semiconductor manufacture sector and the sf 6 production sector (each about 10%).Get price
