摘要
The present invention relates to a method for preparing spherical silica aerogel granules and spherical silica aerogel granules prepared thereby. The method for preparing spherical silica aerogel granules, which is suitable for mass production because droplets of a water glass solution are uniformly dispersed with a uniform size in a non-aqueous solvent using a surfactant in a certain step to reduce a process time and enhance productivity, may be provided. The spherical silica aerogel granules having a uniform size prepared by the method may be provided, wherein the spherical silica aerogel granules have a high working property and excellent flowability.
