Abstract

Vitrification process induced by a ball milling was investigated for silver-ion-conducting materials in the system AgI-Ag₂WO₄. The amorphous materials were obtained over the wide composition range of 30 to 70mol%AgI content. The silver-ion conductivities of a ball-milled sample showed the maximum at a milling time at which the sample was composed of an amorphous phase and a-Ag₂WO₄ crystalline phase. This result suggested that the amorphous phase was containing a large amount of AgI content and the amorphous phase was a high ion conductive phase. The maximum conductivity 4.8×10^-2 Scm^-1 at 298 K was observed for the 70AgI⋅0Ag₂WO₄(mol%) sample ball-milled for 20 h. This conductivity was higher than that of the completely amorphous sample with the same composition.
