MORPHOLOGICAL REGULARITIES IN THE FORMATION OF SILVER-HALIDES DURING IN-SITU HALIDIZATION OF SILVER STEARATE

The results of an investigation of the sites of silver halide formatio n on the surface of silver carboxylate crystals, modeled by silver ste arate and prepared by the standard in situ process used for thermally developed photographic materials, are reported. For the first time the structure of a silver halide/silver carboxylate interface has been cl early observed. Silver bromide is found to form on the edges of the si lver stearate crystal during the initial stages of the reaction. The i nfluence of the nature of the halide source on the silver halide shape and location on the silver carboxylate crystal and the presence of de fects in the silver halide crystals are discussed.
