Abstract

It is known that the fractal dimension experimentally determined for sol-gel transitions of SiO2 shows interesting behavior depending on the amount of the water solvent. A new cluster-cluster aggregation model is proposed which schematically includes the expected complex reaction mechanism. The present numerical simulation performed in two-dimensional space gives a reasonable interpretation of the aggregation and reproduces qualitatively the specific behavior of the fractal dimension experimentally observed.
