Abstract

Three different methods - melt quenching, twin rollers and mechanosynthesis - were used for preparation of the 50AgI•30Ag 2O•20V 2O 5 glass - a good amorphous superionic conductor. It was demonstrated that physical properties of the final amorphous material depend to some extent on the preparation method. As-received samples were characterized by: X-ray diffractometry (XRD), differential scanning calorimetry (DSC), infrared absorption (FTIR), Raman scattering and impedance spectroscopy (IS) in a wide temperature range from -150 to 20 °C. Main conclusion of the results of these studies is that substantially different synthetic routes can be used to produce amorphous materials of very similar but not identical properties. © 2010 Elsevier B.V.
