  • SF6 Worries – The Most Potent and Persistent Greenhouse Gas

    Sep 20, 2019Why worry, leaks!. The discovery of SF 6 can be traced to the work of Henri Moissan and Paul Lebeau in 1901, who found that sulfur reacted with fluorine according to the reaction equation: . S 8(s) + 24 F 2(g) → 8 SF 6(g). Under ambient conditions of temperature and pressure, SF 6 exists as a gas; this property is traceable to the small size and low polarizability of the fluorine atoms
