Collisional Decomposition of sf 6 | 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 is large.
