• 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 fugi

    Sulfur hexafluoride is generally used in present high-voltage circuit breakers at rated voltage higher than 52 kV. Into the 1980s, the pressure necessary to blast the arc was generated mostly by gas heating using arc energy. It is now possible to use low-energy spring-loaded mechanisms to drive high-voltage circuit breakers up to 800 kV.
