Abstract
The present invention provides a crystallization process wherein a starting temperature is selected such that a desirable crystal morphology (e.g., square) is obtained. A temperature shift is then introduced, providing that the shift is not enough to induce further nucleation, where the crystals continue to grow in the desirable fashion, but with different kinetics, e.g., a higher rate of crystallization. As a result, the process gives a crystalline product with desirable morphology at a higher crystallization rate.
