Selfnucleating
Selfnucleating refers to the ability of a substance to form crystals without the need for external nucleation agents. Nucleation is the initial process where a stable cluster of molecules forms in a solution or melt, which then serves as a template for further crystal growth. In most cases, crystallization requires the presence of impurities, seed crystals, or specific surface treatments to initiate this process. However, some substances possess inherent properties that allow them to nucleate spontaneously under appropriate conditions.
This phenomenon is often observed in highly purified materials or when specific thermodynamic conditions are met,
