I've run into an issue that the internet seems ill-equipped to answer, so I turn to the experts. While I'm aware that most fusion experiments to date have used deuterium and deuterium-tritium blends as their fuels, I find myself wondering: can any dielectric material produce energetic plasma under the right conditions? Ignoring the engineering headaches in pumping enough energy into the fuel, attaining necessary compression, and other limiting factors for science, is plasma a fair state of matter for any element and compound, or is there a critical attribute? Moreover, is there any benefit in shifting to a different source material for generating your plasma? If you could produce plasma from, say, sulfur hexafluoride, would it effectively be any different from the plasma produced by a D-T fusion test fire? Or would the only difference be more waste neutron radiation? I really want to get this right (I like my writing to be scientifically accurate as far as the state of the art will allow) and I'm hoping someone can shed some light on this. Many thanks in advance!
