Crystallization nucleus
WebCrystallization - A Primer (with pictures and minimal equations) The High Temperature Gas Phase - recalling the importance of thermal motion. Recall what you already know about … Nucleation can be either homogeneous, without the influence of foreign particles, or heterogeneous, with the influence of foreign particles. Generally, heterogeneous nucleation takes place more quickly since the foreign particles act as a scaffold for the crystal to grow on, thus eliminating the necessity of creating a new surface and the incipient surface energy requirements.

WebThe term primary nucleation is used to describe both homogeneous and heterogeneous nucleation mechanisms in which solute crystals play no role in the formation of new crystals. Primary nucleation mechanisms involve the formation of crystals through a process in which constituent crystal units are stochastically combined.
