摘要
The stages of the evolution of fractally aggregated systems of tetraethoxysilane, which was hydrolyzed in an acidic medium, have been considered. Spherical structures at nucleophilic growth and prepercolation structures and percolation network materials on spinodal decomposition have been obtained. A program which enables one to simulate the growth of fractal aggregates both in two-dimensional and three-dimensional space has been designed.
