  • Hexafluoride - Wikipedia

    From Wikipedia, the free encyclopedia A hexafluoride is a chemical compound with the general formula QX n F 6, QX n F 6m−, or QX n F 6m+. Many molecules fit this formula. An important hexafluoride is hexafluorosilicic acid (H 2 SiF 6), which is a byproduct of the mining of phosphate rock.

  • Sulfur hexafluoride circuit breaker - Wikipedia

    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.
