Fractal approach of nucleation in liquid and gas phases

Abstract

g→+ In the kinetic equations derived by taking into consideration nucleation and nuclei growth, the fractal character of the new phase nuclei was introduced. In this note a higher generality of the gas phase or liquid phase nucleation fractal treatment is suggested. This treatment enables to describe, in principle, besides the generation of the solid product from gas phase reactants, crystallization from liquids and solutions and precipitation [6]. For the quantitative treatment the bulk disappearance of the potential nuclei which turn into real ones should be considered. Besides one has to take into account that potential nuclei can disappear due to the surface reaction as they could be incorporated by the growing nuclei [6]. One has to mention that nucleation can be normal or it can occur according to a branched chain mechanism.
