โœฆ Synopsis

New layered perovskite compounds, AgLaTa,O, and AgCa,Ta,O ,,), have been synthesized by an ion-exchange reaction from parent compounds, RbLaTa,O, and RbCa,Ta,O,,.

The crystal structures of silver ion-exchanged compounds were determined by the Rietveld analysis for powder XRD patterns. These compounds, which are probably metastable, could only be obtained by the ion-exchange reaction. The relatively high ionic conductivities attributed to the interlayer silver ions were observed at high temperatures.
