Temperature variations in an SF6-N2 mixture arc plasma

2019-4-10 · mixtures in general and by SF6-N2 mixtures in particular has been considered a possible solution to this problem. The experimental study of these mixed plasmas, except for the case of air, has been less extensively studied. We present here the results of temperature measurements in a steady state arc plasma burning in an SF6-N2 mixture.

Separation of SF6 from Binary Mixtures with N2 Using

2018-6-6 · Systematic studies on gas permeation of pure SF6 and N2 as well as their mixture in poly(4-methyl-1-pentene) (PMP) at different temperatures and pressures, using commercially available thin PMP films, are reported in this article. The effective separation of SF6 from binary mixtures with N2 is critical for the proposed replacement of pure SF6, used as an insulating gas in high power industry
