An investigation was made of ternary glasses, AgI–Ag2S–AgPO3, where the AgI:Ag2S ratio was 1:1. It was found that, as the amount of dopant salt increased, the glass transition temperature decreased and the room-temperature conductivity increased to about 5.7 x 10-3S/cm for an 88mol% fraction of AgI+Ag2S. The structure factor exhibited a pre-peak at low Q-values (0.6 to 0.9/Å); as observed in AgI–AgPO3 glasses but not in pure AgPO3 or in Ag2S–AgPO3. The concentration dependence of the pre-peak indicated the existence of medium-range atomic correlations that grew in concentration and size.
