Superionic conduction in this amorphous electrolyte system was studied (table 234). The glass-former/modifier ratio, and the AgI concentration were varied continuously in order to establish the glass-forming domain of the system. Differential scanning calorimetry and X-ray diffraction were used as sensitive probes. Transport studies and infra-red absorption spectroscopy were used to characterize xAgI - (100-x)(Ag2O-CrO3) glasses and to help to clarify the conduction process and the possible structural units in these electrolytes.
