Estimation of metastable zone width in different nucleation processes

Estimation of the metastable zone width has been explored by using models b ased on the fact that metastable zone width is determined by the nucleation mechanisms acting within a crystallizer. Calculations were carried out for three organic systems and 28 aqueous inorganic systems at the various cool ing rates and compositions. Both seeded and unseeded systems have also been applied to the calculations. The models developed were verified with publi shed experimental data. About 150-data points of metastable zone widths mea sured from bench-scale crystallizer were compared To those obtained by the model. Theoretical model could be used for the prediction of metastable zon e width for various nucleation processes. (C) 2001 Published by Elsevier Sc ience Ltd.
