sf6 o2 Products Quantitative

Sulfur hexafluoride (SF 6) or sulphur hexafluoride (British spelling), is an extremely potent and persistent man-made greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom.

  • Study on Pyrolysis Characteristics of SF6 in a Trace

    The relative quantitative relationship between SOF2 and SOF4 can be used to determine the fault temperature. Besides, under overheating conditions, O2 rarely undergoes a self-cracking process to generate free O atoms. Instead, the basic route for O2 to participate in the SF6 pyrolysis process is X + Y + O2 = XO + YO.Author: Heng Liu, Jian Wang, Jingrui Wang, Qi Hu, Yanan Chang, Qingmin Li

    May 01, 1970At 10 Torr CI~(SFt/CI2 = 22) the extent of SF6 oxidation.was only slightly higher than for simple SF6/O2 mixtures, but at 100 Torr C12(SF6/C12 = 2.2) the extent of SF6 oxidation was twice that of the SF6/O2 system. This effect tends to level off, however, because 300 Torr CI~ was no more effective than 100 Torr CIr.Cited by: 5
