WebApr 8, 2024 · Crystallization is a natural process which happens when the materials solidify from a liquid, or as they precipitate out of a liquid or gas. This process can be carried out by causing a physical change, like a change in temperature, or a chemical change like acidity. The crystallization process is carried out on the basis of the size and shapes ... WebA liquid crossing its standard freezing point will crystalize in the presence of a seed crystal or nucleus around which a crystal structure can form creating a solid. Lacking any such nuclei, the liquid phase can be maintained all the way down to the temperature at which crystal homogeneous nucleation occurs. [5]
