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… WebMay 12, 2024 · Crystal growth is one of the industry’s largest challenges in agrochemical suspension concentrate (SC) formulations, as it causes severe …
