  • Oxidation of sulfur hexafluoride - ScienceDirect

    Clearly, the SF6 oxidation must be intrinsically very much slower than the methane pyrolysis. It would appear that the lower rates of SF6-O2 reactions, even at very high temperatures, drastically influence the product profiles and the extent of per- manent energy abstraction. This does not appear to be related to the small mass of the exploded metal.
