• Sulfur hexafluoride | F6S - PubChem

    The amount of sulfur hexafluoride in the atmosphere totaled 589 metric tons. This amount increases by 7% every year. If released to water or soil, it is not expected to bind to soil particles or suspended particles. Sulfur hexafluoride is expected to move through soil. Sulfur hexafluoride is expected to move into air from soils or water surfaces. Sulfur hexafluoride is not expected to be broken down by microorganisms and may not build up in tissues of fish.

    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 fugi

To fix both FOVs at 10 cm, the gradient increment, ΔG, was set to 0.53 G/cm for H 2 and 0.42 G/cm for SF 6. The rf pulse width for both gases was set to 6 μs with a flip angle α of 49° for hydrogen and 19° for sulfur-hexafluoride. Eight signal averages were collected for hydrogen gas imaging and 16 for sulfur-hexafluoride gas imaging, with 16 FID points collected for each.

    Although sulfur hexafluoride is nontoxic and nonflammable, escaped gas in enclosed rooms displaces oxygen in the air and could lead to asphyxiation. SF 6 is also a potent greenhouse gas – 23,900 times more effective than carbon dioxide at trapping infrared radiation in the atmosphere. In addition, TD plant safety depends on the purity of SF 6 gas. Under normal conditions during an electrical discharge, the six fluorine atoms split from the sulfur atom to capture electrons; after quenching
