WebFeb 4, 2024 · Crystallization is a collection of the subprocesses of crystal primary nucleation, crystal growth, secondary nucleation and agglomeration, which are all governed by the prevailing supersaturation as well as other parameters. The rates of these subprocesses determine the crystalline product quality. WebHowever, because crystallization is most often employed as a purification process, numerous impurities resulting from the upstream part of the process are necessarily present in solution, such as buffer components, residual reactants, intermediates, or by-products.
