Abstract

The heterogeneous exchange process of mixed AgI + PbI2
precipitates with iodide from the KI solution was studied using 1311.
The systems under examination were prepared in statu nascendi at
293 K. Radiometrically determined solubility, differential thermal
analysis and X-o:-ay diffraction analysis data were compared with
radi:oanalytical results of the heterogeneous exchange processes. The
results show ,strong mutual dependence of the metal halides present
throughout the exchange process. The quantitative analysis of
radiometric data indicates the specific influence of lead iodide onto
silver iodide particles during the Ostwald's ripening process.
