Analysis of Acoustic Spectra Reflecting Ion Transport Processes in Glassy Electrolytes

The investigation of acoustic spectra in ion conductive glasses wiht different composition can reflect the basic features of the relaxation and transport processes of the mobile ions. It was found that the temeperature responses of all acoustic spectra are very similar and the relaxation peaks associated with ion transport depend on the galsss composition. Experimental and theoretical aspects of acoustic attenuation measurements in ion conductive glasses of the system Cul-CuBr-Cu2O-P2O5 are reviewed. Theoretical studies of acoustic spectra due to the ionic hopping motion and relaxation processes connected with the mobility of Cu+ conductive ions are compared with experimental results and some attempts to fit the acoustic attenuation spectra are accomplished.
