Influence ofdifferentmixingdevices and surfactant Laprol 3603-2-12 on the formation of tabular silver halidemicrocrystals inthe photographic emulsion has been investigated using scanning electronmicroscopy. Values of theLaprol concentrations forhomogeneityincreasing,obtainingofbimodalemulsion and for transformation crystals fromtabular to octahedralonehavebeenestimaited.Our experiments have shown that the Laprol is a powerful factor to control size distribution and the shape of the silver halidemicrocrystals in the gelatin solution.
