| Abstract: | The compound Ag14Sb12O36F2, with a desordered KSbO3 cubic structure, is obtained by an ion exchange method. The conductivity of the silver ions in both Ag14Sb12O36F2 and AgSbO3 pyrochlore compounds is investigated by measurement of complex impedance. The e.m.f. measurement and curves i vs. E show that the conduction is essentially assumed by Ag+ ions. This study confirms that the cubic KSbO3 framework structures are good candidates for ionic conductors. |
