A new method of obtaining a ZnO-SiO₂ synthetic composite from emulsion systems is described. The reagents were solutions of sodium silicate and zinc sulphate, cyclohexane was used as an organic solvent and non-ionic surfactants as modifiers. The influence of the mode of reagents dosing and type of emulsifiers on the physicochemical properties, structure and particle size of ZnO-SiO₂ was evaluated. The choice of the optimum emulsifier or mixture of emulsifiers and their amounts needed for the process of precipitation and ensuring getting products of uniform particles and the smallest possible size was proposed. The ZnO-SiO₂ composite obtained was characterised by micrometric particle size. The oxide composites obtained were subjected to thorough analyses to determine their physicochemical properties, dispersion and morphology. Particle size distributions were evaluated by the NIBS technique and laser diffraction method. The products were also characterised by sedimentation profiles, wettability with water and colorimetric analyses, determination of bulk density or ZnO and SiO₂ contents.
