Development of nanotechnology suggest two approaches to the creation of nanostructured materials: «top-down» and «bottom-up». The first one considers the ultra-dispersed substance and the subsequent formation of the material. Second - the synthesis of nanoparticles through chemical reactions of atoms and molecules as a basis for forming material. In both approaches, the nanoparticle is a central figure in the understanding of the formation of the nanomaterial. The purpose of this study is to simulate the formation processes of nanoparticles in the sol-gel method by hydrolysis of tetraethoxysilane or silica.
