✦ Synopsis

The effect of mechanical treatment on the crystal structure of AgI was studied by X-ray diffraction and EXAFS techniques. It was shown that even moderate mechanical treatment of AgI results in the appearance of stacking faults in a close-packed anion sublattice. After an intense mechanical treatment the random P-y polytype structure is formed. The polytypes are built of domains separated by antiphase boundaries which are the most probable sources of cationic Frenkel defects governing the high ionic conductivity and anomalous dielectric properties of mechanically treated Agl.

Dielectric properties of mechanically treated AgI are studied within the frequency range 20 Hz-l MHz. Contribution of the electrode polarization was eliminated and the dielectric permittivity of polycrystalline Agl was extracted. Dielectric properties of mechanically treated AgI are typical of relax

It is shown that the increase in conductivity of polycrystalline silver iodide due to its mechanical treatment can be attributed to the presence of metastable defects which are formed on mechanical treatment of AgI. Defects may be annealed by heating with the annealing rate depending on purity of Ag
