Abstract

The electrical conductivity, κ, of pure and sodium doped sulfur melts was measured with and without ultrasonic waves at temperatures ranging from 140 to 340°C by the two probe method using an ultra high resistance meter. The κ value of the pure sulfur melt with irradiation jumped at around 170°C by an order of 102 after which it monotonically increased from 10-5 to 10-4 Ω-1 cm-1 with an increase of the temperature. The addition of the sodium metal to the sulfur melt was found to cause a larger jumping in the κ value. The κ value increased with the increase of Na proportion in the melt. For a 10 mol% Na doped sulfur melt it was as high as max. ∼30 Ω-1 cm-1 above 180°C under the irradiation of ultrasonics.
