We have investigated the ternary glass AgI-Ag2S-AgPO3, where the ratio of AgI:Ag2S is 1:1. As the amount of the dopant salts increases, the glass transition temperature decreases, and the conductivity increases to about 5.7×10-3(Ωcm)-1 at room temperature for an 88% mol fraction of AgI+Ag2S. The structure factor, S(Q), shows a prepeak at low Q values (0.6-0.9 Å-1), as observed in AgI-AgPO3 glasses, but not in pure AgPO3 or in Ag2S-AgPO3. The concentration dependence of the prepeak indicates medium range atomic correlations growing in concentration and size.
