The conductivity of 2 families of super-ionic glass-ceramic composites: AgI-(50-x)Ag2O-xV2O5 (where x ranged from 14 to 25) and xAgI-(80-x)Ag2O-20V2O5 (where x ranged from 30 to 50) was studied. The composites were prepared by annealing initially amorphous samples, with the given composition, at temperatures which slightly exceeded the crystallization temperature. The formation of crystallites was revealed by the X-ray diffraction patterns of the annealed samples. The structural changes which were produced by annealing were closely related to the changes in ionic conductivity. The conductivity of the resultant composites, at high temperatures, was greater than that of the original glass. Moreover, it did not change (over a period of some hours) at stabilized temperatures which exceeded the glass transition temperature. The conductivity of the glasses was thermally stable only below the glass transition temperature. The highest conductivity (0.1S/cm at 150C) was close to that found for the best super-ionic conductors at these temperatures.
