Electric arc/plasma resistant gas

  1. Jul 28, 2011 #1
    Im looking for a gas which is resistant to electrical arcing and turning into plasma, preferably being easy to obtain and handle, as well as being as light as possible. (Like helium). Thanks!

    EDIT: More research suggests sulfur hexaflouride or (maybe) nitrogen. http://en.wikipedia.org/wiki/Dielectric_gas

    Sulfur hexafluoride (SF6) is a gas used in waveguides to reduce arcing. However, I'm not sure if it is "easy" to handle. It is a greenhouse gas. And it is heavier than air, so it isn't "light".

    Argon, helium, carbon dioxide, nitric oxide and others are used in electric arc welding as a shielding gas. Some of those gases may suit your purpose.
