  • Oxidation of sulfur hexafluoride - ScienceDirect

    Because exploding metals react chemically with both SF6 and Oz, it becomes necessary to explode extremely small metal masses, if one wishes to study only SF6-O2 reactions. Ideally, if the metal/SF6 ratio is _sufficiently low, the explosion of the metal serves only to transfer energy from the storage capacitors to the 1. H. L.Cited by: 7
