Synthesis of titanium-oxygen layers on silicon oxide monodisperse particles and comparison between the electrosurface characteristics of the initial and modified particles

Synthesis of titanium-oxygen layers was carried out on the surface of spher ical monodisperse particles of silicon oxide 0.56 mu m in diameter. For the initial particles and those modified with titanium oxide, the electrokinet ic potential and adsorption of potential-determining ions were measured dep ending on pH at the background of 1 : 1 electrolytes. It was established th at the deposition of even the first layer of titanium oxide shifts in the i soelectric point (IEP) to a value close to the IEP of the bulk oxide synthe sized under similar conditions.
