Studies were performed on a group of highly dispersed silicas, formed using precipitation technique. The silicas were precipitated in an emulsion system from sodium metasilicate solution, using hydrochloric acid supplemented with emulsifiers and an appropriate amount of organic phase (cyclohexane, hexane, heptane, octane). The dispersion was induced using a homogenizer. The studies permitted to obtain SiO2 particles of optimum particle diameter and a defined spherical shape. For the obtained products, also the profiles of wettability and sedimentation in water were determined.
