Аннотация
A new model for the kinetics of homogeneous nucleation of crystals from melts is developed in the framework of classical nucleation theory. The traditional approach considering the mechanism of mass transfer from the melt to nucleated particles by random attachment of atoms at the interface, which is valid for crystals with atomically rough interface, is modified in application to faceted crystalline particles with atomically smooth interface, whose growth is controlled by two-dimensional nucleation of terraces of monoatomic height on the crystal faces. The new model demonstrates a strong suppression of the nucleation rate compared to the traditional approach.
