摘要: Abstract In order to simulate the precipitation of silver bromide octahedral crystals, a model is developed, which encompasses main kinetic and thermodynamic features crystallization including primary nucleation, as well equilibria in solution. The then validated during three steps (nucleation, ripening growth) experimental precipitations, are supposed be performed under mixed conditions. unknown parameters nucleation process fitted data through model. These investigations will contribute better understanding process, shown most critical moment for shape final crystal size distribution (CSD). Nevertheless, duration step so short nuclei small that no quantitative results can expected. Finally, mixing effects were observed seemed play major role step.
