Abstract
Plasmas consisting of a high-ionization-potential component mixed with a low-ionization-potential contaminant are common in industrial processes. Modeling results are presented for a sodium-contaminated nitrogen plasma column operating either in a free-burning (low-temperature) mode or operating in a constricted (high-temperature) mode. At sufficiently high plasma temperatures, the behavior is dominated by the high-ionization-potential component's properties. The low-ionization-potential contaminant's properties determine the low-temperature plasma behavior even when the contaminant is present in relatively small quantities.
