0.85AgI-0.15Ag_4P_2O_7 glass was prepared by the liquid nitrogen quenching technique, and the Ag~+ conductivity at room temperature was measured as 1.4 × 10~(-2) S / cm. A gradual crystallization was detected by XRD analysis for the glass samples treated at a certain heating rate. And the conductivity of the glass sample was deviated anomalously from the Arrhenius' linearity as the temperature was increased. The ESR spectra intensities were weakened linearly with the increase in temperature of the crystallized glass samples which were doped with trace amount of Mn~(2+) or V~(4+) ions as spin probe. The results along with the structural changes and the interface effect on the ionic conduction in the crystallization process of the amorphous solids are discussed.
