Glass phases showing high ionic conductivity at room temperature were prepared through a rapid quenching of molten mixtures of the system Ag 2 S‐AgPO 3 ; the specimens obtained were homogeneous and transparent cylindrical blocks. Room‐temperature conductivity data show a monotonic increase with x ag2 s in the glass‐forming range. Linear fits of the Arrhenius plots of the bulk conductivity were obtained in the 290 K to T g (glass‐transition temperature) range. The transport numbers of Ag ions in the glasses were measured by the emf method. The results show that all glasses in this system are practically pure ionic conductors due to the presence of Ag ions, so that they may be regarded as solid electrolytes.
