WebThe liquid concentration decreases upon crystal nucleation and stays close to the solubility curve. At the end of the antisolvent addition period, the liquid concentration drops to the solubility curve. When antisolvent is added at the faster rate, the supersaturation level is higher throughout the process - due to a buildup that cannot be ... WebThe mechanisms by which impurities and additives dissolved in solution affect the crystallization process can be rationalized in a common framework, so they will both be placed under the umbrella of foreign species in this chapter. The species to be purified will instead be referred to as the host species. Type Chapter Information

After successful formation of a stable nucleus, a growth stage ensues in which free particles (atoms or molecules) adsorb onto the nucleus and propagate its crystalline structure outwards from the nucleating site. This process is significantly faster than nucleation. The reason for such rapid growth is that real crystals contain dislocations and other defects, which act as a catalyst for the addition of particles to the existing crystalline structure. By contrast, perfect crystals (lackin…
