The compound Ag//1//4Sb//1//2O//3//6F//2, with a disordered KSbO//3 cubic structure, is obtained by an ion exchange method. The conductivity of the silver ions in both Ag//1//4Sb//1//2O//3//6F//2 and AgSbO//3 pyrochlore compounds is investigated by measuring their complex impedance. Emf measurement and current-voltage curves show that the conduction is essentially assumed by Ag** plus ions. This study confirms that the cubic KSbO//3 framework structures are good candidates for ionic conductors.
