ABSTRACT
In this paper, the contrasting properties of titanium dioxide nanoparticles in various compositions were considered. In the course of the work, methods for the synthesis of oxide materials SiO2-TiO2, SiO2-ZrO2, TiO2-ZrO2 and SiO2-TiO2-ZrO2 were developed;the microstructure of oxide materials SiO2-TiO2, SiO2-ZrO2, TiO2-ZrO(2)and SiO2-TiO2-ZrO(2)was studied;the stability of oxide materials SiO2-TiO2, SiO2-ZrO2, TiO2-ZrO(2)and SiO2-TiO2-ZrO2 was determined. The elemental composition of the oxide materials SiO2-TiO2, SiO2-ZrO2, TiO2-ZrO(2)and SiO2-TiO2-ZrO2 has also been studied using SEM and XRD methods. It was found that SiO2-TiO2-ZrO2 nanocomposites with content of titanium dioxide from 8 to 9.5 % and zirconium dioxide from 0.5 to 2 % are completely insoluble in a highly alkaline medium. Thus, this composition is the most optimal for use as a contrast agent in optical coherence tomography.
