Silicic Acid Polymerization and SiO Nanoparticle Growth in Hydrothermal Solution.
Polymers (Basel)
September 2022
The approach of numerical simulation of orthosilicic acid OSA polymerization and SiO nanoparticle formation in hydrothermal solution have been developed based on the model of the homogeneous stage of nucleation and the subsequent growth of particles. The influence of surface tension on the interface of SiO-water, the rate of molecular deposition, and Zeldovich factor Z were evaluated. Temperature dependence on time, pH, initial OSA concentration, and ionic strength are the main parameters that determine the kinetics of colloid phase formation, the final average size of SiO nanoparticles, and the particle size distribution and its polydispersity index.
