Plasmas are chemically active media. Depending on the way
they are activated and their working power, they can generate
low or very high ‘‘temperatures’’ and are referred correspondingly
as cold or thermal plasmas. This wide temperature range
enables various applications for plasma technologies: surface
coatings, waste destruction, gas treatments, chemical synthesis,
machining. . . Nevertheless, many of these techniques have not
been industrialized, albeit environmental norms are strictly
followed.
