Abstract:
The present invention relates to a method for separating and collecting single aggregates from fumed silica, and a method for classifying a shape of the collected single aggregates, and more specifically, includes preparing a slurry in which fumed silica is dispersed in water; aerosolizing the slurry; and collecting single aggregates of the finned silica in the aerosol using the electric field.
