Abstract. A particular attention is paid to the experimental study of transport mechanisms in glassy materials with the fast ion transport that play an important role in a number of modern electrochemical devices. The investigation of conductivity spectra of ionic glasses is the basic tool for transport mechanisms study. However, the acoustic attenuation measurement is another very useful technique for non-destructive investigation of transport mechanisms in conductive glasses that can have even some advantages comparing to electrical ones. In the contribution we present both acoustic and conductivity spectra of new phosphate glasses containing Cu+ conductive ions in the system CuI-CuBr-Cu2O-P2O5 with respect to investigate ion transport mechanisms and to determine the relation between acoustical and electrical properties considering the various glass compositions.
