“…Hydrothermal synthesis of SiO 2 nanoparticles is the new technological method with a low production cost, high density of silanol groups, low toxicity, excluding the use of chemical reagents and other green chemistry methods of nanoparticle synthesis [ 1 , 2 , 3 ], and allows to obtain different forms of nanosilica—sols, gels, powders, products of the sol-gel process applied in concrete, agricultural plants, medicines, and other materials [ 4 , 5 , 6 , 7 ]. The technology of hydrothermal synthesis includes the stages of OSA polymerization, ultrafiltration membrane concentration of nanoparticles, the sol-gel process, vacuum sublimation, and others [ 4 , 5 , 6 ]. The temperature regime, the stage of polymerization, pH, initial OSA concentration C s , and ionic strength influenced the rate of SiO 2 nanoparticle formation, the average nanoparticle size, and the index of polydispersity of nanoparticles in hydrothermal sols.…”
