Collisional Decomposition of sf6 gas | NIST

Sep 01, 2000 · Abstract Insulating gas mixtures containing SF 6 have been promoted to serve as replacements for pure SF 6 in order to reduce SF 6 atmospheric emission. It has been argued that some synergism may be achieved by choosing proper buffer gases in mixtures with SF 6 such that the buffer gases efficiently slow down electrons into an energy range where the electron attachment cross section for SF 6

insulating gas Decomposition in Gas-Insulated Equipment - IEEE Journals

Abstract: The increasing application of sf 6 as an insulating gas has led to many studies on sf 6 decomposition in gas-insulated equipment. In the presence-of an electric arc, spark or corona, sf 6 decomposes to a wide variety of chemically active products which possess completely different properties from sf 6.
