Abstract: Water suspensions of nanosized silica dioxide are obtained by dispersing in a liquid medium. The influence of sonication time on the size of the silica particles is investigated. It was shown that ultrasonic treatment with simultaneous mechanical mixing and the introduction of surfactants lead to the formation of larger number of particles with smaller size.

Keywords: ultrasonic dispergation, pyrogenic silica dioxide, nanosized particles, cavitation, hydrodynamic diameter.
