Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for preparing a stabilized aqueous dispersion and a silicic acid dispersion without having a high electrolyte content or salt content. SOLUTION: The aqueous dispersion, which contains at least two chemically different particle types having a mean diameter of less than 100 μm, can be obtained. The process for preparing the silicic acid dispersion, wherein water and at least one particle type which differs chemically from silicic acid are initially introduced into water, and silicic acid is then added with application of a shearing energy.
