%X High-energy ball-milling process is a powerful method for the preparation of amorphous phases, nanocrystalline materials, and so on. In this paper, we applied the high-energy ball-milling process to the synthesis of superionic conducting amorphous materials with Ag2S content of 80 mol%. Ball milling of 12h to 20h led to the formation of amorphous phases in the composition. The amorphous samples showed very high ionic conductivities, among which the 20h-ball-milled sample presented the maximum conductivity of 2.96×100Sm-1 at 298 K. Further ball milling resulted in partial precipitation of Ag8SiS6 crystalline phase, therefore, a decrease in ionic conductivity was observed for the samples ball-milled for longer than 27h. DC polarization measurements suggested that the ion transport number of the amorphous samples and the ball-milled samples containing some Ag8SiS6 crystalline phase, together with that of the Ag8SiS6 crystal, was practically unity.
