Simulation of the precipitation of silver bromide photographic emulsions

摘要: Nucleation and crystal growth processes involved in the batch precipitation of photographic emulsions by addition silver nitrate to an aqueous solution bromide gelatin have been reasonably successfully modeled. Simulation predicts known increase average size with increased time, temperature, halide levels. Solubility is related Gibbs-Thomson equation. The predicted decrease number crystals during course similar published data, but there are quantitative differences. model very sensitive variations constant equation, not constants nucleation
