TL;DR: In this paper, the authors measured the width of the metastable zone of concentrations under varying conditions and found that the nucleation rate at the beginning of nucleation will be identical with the supersaturation rate for a limited period of time.

TL;DR: In this paper, a method for the calculation of optimum cooling curves based on a simple mathematical description of the individual kinetic processes involved in a crystallization operation is presented, and the results show that the programmed cooling brings about a significant increase in the size and an improvement in the quality of crystals from a batch crystallizer.

TL;DR: In this article, the metastable zone-widths of 25 different systems and their dependence on the cooling rate, the temperature and the presence or absence of crystals are reported and the results are discussed.

TL;DR: In this paper, the fundamental physics of kinetics concentration supersaturation crystal growth and nucleation rates growth rate expressions size dependent growth and growth rate dispersion shape factors size distributions nucleation rate expressions methods of growth rate measurement fixed single crystals rotating disc batch multiparticle systems continuous MSMPR crystallizer mechanical material properties relevant for attrition methods of growing rate measurement metastable zone width measurements rates of primary nucleation.

TL;DR: In this article, an analysis of the programmed cooling of batch crystallizers, starting with the solution of the momentum equations of the population balance, is presented. But the model described in this paper determines the optimum cooling curve for a batch crystallizer with an arbitrary seeding and nucleation ratio.
