Crystallographic analysis of atomic structures in the study of crystallization mechanisms

Abstract

By means of the mechanical-wave concept of crystal state and the crystallographic analysis the universal regularities of the crystal structure formation are determined: presudotranslational ordering of atoms within unit cells; separate ordering of different groups of atoms with the alignment of their sublattice parameters; the principle of coherent assembly a structure from stable building blocks with the local geometry and block symmetry spread on the structure formed, and so on. The crystallization mechanism is illustrated by specific structures.
