Crystal Formation (Nucleation) of Silver Halides – Comparison of Models
Ingo H. Leubner, Proceedings of the 45th Annual Meeting of the Society for Imaging Science and Technology (IS&T), E. Rutherford, NJ, p.13-17 (1992)
Crystal nucleation theories and their scope and limitations with regard to silver halide precipitations were reviewed. These include the classical, primitive, and Klein-Moisar models. The nucleation model based on dynamic mass balance and crystal growth mechanisms (BNG) was compared to these other models.
The predictions of the BNG model for the dependence of crystal nucleation on addition rate, solubility, and temperature were confirmed by experimental results for silver halides. The results support the BNG over other crystallization models.
The BNG-predictions for changes in crystal morphology of AgBr with increasing solubility (pAg) were first experimentally supported, presented, and published at this occasion.
