The method developed for determining size‐dependent crystal growth kinetics makes use of the assumption that the linear growth rate is a product of a size‐dependent factor and a supersaturation‐dependent one. The transformed form of the population balance equation, obtained by means of this assumption, is the basis of the evaluation utilizing measurement data from one seeded batch crystallization experiment, namely the size distributions of the seed and product crystals as well as the supersaturation course. The application of the method is illustrated by evaluating an experiment with potash alum crystals.
