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.
