Ionic Conductivity of Prussian Blue Typecompounds Doped with Alkali Metal Chlorides

Abstract

Prussian blue type compounds (heavy metal ferro and ferricyanides) doped with alkali metal chlorides are found to exhibit alkali-metal ion conducti vity. An unusual property of these systems is that the highest conductivity is obtained for K+. Ferric ferricyanide doped with KCI under optimum conditions is found to have a room temperature (26°C) conductivity of 5xlO'! ohm cm'
