Description
Electrical conductivity measurements were made of 95CaS–5Na2S solid solution at 723 K through 1173 K under a sulfur partial pressure range from 10−10 to 103 Pa with an alternating current bridge. The compacted 95CaS–5Na2S disks were sintered at a temperature of 1323 K because the sublimation of Na2S became significant over 1373 K.<BR>The conductivity of the 95CaS–5Na2S solid solution was independent of the sulfur partial pressure, and its temperature dependence can be expressed as<BR>log(σ⁄(S·m−1))=−3.12×102⁄T−1.407 (723–1173 K).<BR>The apparent activation energy for electrical conductivity was 5.97 kJ·mol−1.<BR>An electrical resistance change with time was found for potentiostatic electrolysis of 95CaS–5Na2S.<BR>These results lead to the conclusion that the 95CaS–5Na2S solid solution is an ionic conductor.
