hexafluoride system Wuhan huayi

Sulfur hexafluoride is a sulfur coordination entity consisting of six fluorine atoms attached to a central sulfur atom. It is the most potent greenhouse gas currently known, with a global warming potential of 23,900 times that of CO2 over a 100 year period (SF6 has an estimated lifetime in the atmosphere of between 800 and 3,000 years).

  • Hexafluoride - Wikipedia

    A hexafluoride is a chemical compound with the general formula QXnF6, QXnF6m−, or QXnF6m+. Many molecules fit this formula. An important hexafluoride is hexafluorosilicic acid, which is a byproduct of the mining of phosphate rock. In the nuclear industry, uranium hexafluoride is an important intermediate in the purification of this element.

  • Synthesis and Dielectric Properties of

    Abstract. Sulfur hexafluoride (SF 6) gas has been used in large-scale electrical equipment, because of its excellent high-voltage dielectric strength. However, SF 6 has been identified as a greenhouse gas, because of its high global warming potential (GWP) and extended lifetime in the atmosphere. Based on theoretical calculations, trifluoromethanesulfonyl fluoride (CF 3 SO 2 F) is a relatively eco-friendly gas with a lower GWP than that of SF 6, and the electrical performance of CF 3 SO 2 F
