Silver ion-conducting materials were synthesized for the composition xAgI⋅(100-x) (0.6Ag<SUB>2</SUB>S⋅0.4SiS<SUB>2</SUB>) (mol%) (0≤x≤90) by use of high-energy ball-milling process. Ball milling more than 40h led to the formation of amorphous samples in the composition range of 0 to 65 mol% AgI. On the other hand, the ball-milled samples with AgI content more than 70 mol% composed of amorphous phase and γ-AgI crystalline phase. Silver ion conductivity of the amorphous samples exponentially increased with an increase in the AgI content, and activation energies for conduction correspondingly decreased. The ball-milled 65AgI⋅21Ag<SUB>2</SUB>S⋅14SiS<SUB>2</SUB> (mol%) sample showed the highest silver ion conductivity of 2.7×10<SUP>0</SUP> Sm<SUP>-1</SUP> at 298 K and the lowest activation energy of 20.5 kJmol<SUP>-1</SUP> among the obtained amorphous samples.
