Аннотация
SiO2 sols and nanopowders are produced from hydrothermal solutions using the following processes: polycondensation of orthosilicic acid, ultrafiltration membrane concentration, and cryochemical vacuum sublimation. The physical–chemical characteristics of SiO2 sols and nanopowders are determined: particle size distribution, specific surface area, viscosity, and impurity ions content. It is demonstrated that the size of SiO2 nanoparticles in sols and nanopowders could attain 5–100 nm. The possibility of applying the produced silica to strengthen the concrete is justified.
