- Аннотация: A lot of parameters determine the size distribution of titania spherical particles synthesized by hydrolysis of the titan (IV) - butylate at water-alcohol mixtures. For some applications, it is necessary not only to obtain particles with good diameter monodispersity, but also to maintain the activity of their surface. Therefore, the synthesis of such particles can not always be carried out using surfactants. This paper shows the possibility of synthesizing monodisperse spherical titanium dioxide particles with an average diameter from 0.3 to 1.5 microns without surfactants. Varying of the specific surface area of these particles in the range of from 300 to 100 m2/g have been done by hydrothermal treatment in water at temperature up to 220℃ and during time treatment up to 48h.
