Nucleation in Phase Transitions.

摘要: An understanding of nucleation processes is fundamental in the preparation of all types of colloidal dispersions bycondensation methods. For example, in meteorology, there is fog formation and the artificial production of rainby seeding with appropriate nuclei; in metal-lurgy, the initiation and production of new phases which profoundly affect the physical properties; and in chemical engineering, supercooling, superheating, overcompression, and production of supersaturation and precipitation by chemical means. Controlled relief of …
