Гетерогенное зародышеобразование алмаза в области его метастабильности

Abstract

Theoretical analysis of the heterogeneous nucleation centers formation at strong, average and weak interaction of a base with a precipitate was made. On the basic of the analysis results and formation works of the two-dimentional nucleation centres calculations it was made the conclusion that at the small oversaturations the structure inhomogeneity has a control effect on the diamond crystal growth. Two-dimentional nucleation centres formation has a control effect on that at the high oversaturations
