COLD PLASMAS: ELECTRICAL CONDUCTIVITIES OF SODIUM-AMMONIA SOLUTIONS

Abstract

Electrical conductivities of sodium ammonia solutions have been measured from -80 to 185 C, covering the complete liquid range and in the case of dilute solutions, some of the gaseous range. The objective of these measurements is the evaluation of these solutions as media for gaseous plasmas studies. The attractive features of these solutions are long lifetimes (the plasma being at equilibrium), temperatures as low as 133 C, and high electrical conduct ivities. In the experimental data for the liquids, conductivity maxima occur above 80 C. In the case of dilute solutions, the maxima temperatures are close to the critical tem peratures. Because of this, conductivities of supercritical gases have been measured which are higher than the corresponding liquid con ductivities at room temperature.
