Analysis of nucleation and crystal growth data using the interfacial supersaturation

Using a laboratory-scale fluidized-bed crystallizer as the experimental apparatus, the objectives of this research were twofold. First, after the crystal growth rates were measured, interfacial supersaturation, the mass-transfer, and surface-reaction coefficients were determined from the two-step model using two different methods to check the results. Second, it was hoped to correlate the secondary nucleation rate with interfacial supersaturation and overall supersaturation in order to confirm the hypothesis that both supersaturations contribute to the secondary nucleation rate. Recently, it was found that the growth rate dispersion has an effect on nucleation rate. However, considering the present experimental technique that nucleation rate was estimated by counting the number of nuclei formed, the dispersion effect was negligible.
