Crystallization behavior of nanodisperse phases

Extensive experimental work demonstrates that the crystallization leading to the formation of a nanocrystalline phase is characterized by the following specific features: particles of the solid phase nucleate in a small region of the system where a high supersaturation is produced (local character of the process); crystallization involves a few, kinetically self-similar stages (multistage character); several structural and morphological forms may develop concurrently during crystallization (multiple paths). The information accumulated to date provides the basis for quantitatively describing all the stages of crystallization and optimizing the synthesis of nanomaterials
