METHOD OF PREPARING FOR SPHERICAL SILICA AEROGEL GRANULES AND SPHERICAL SILICA AEROGEL GRANULES PREPARED THEREBY

摘要

The present invention relates to a process for producing spherical silica aerogel granules and spherical silica aerogel granules produced thereby, in which a surfactant is used in a specific step to uniformly disperse droplets of a water glass solution in a non-aqueous solvent in a uniform size, By shortening the time to increase the productivity, it is possible to provide a method for producing spherical silica aerogel granules suitable for mass production, and by this manufacturing method, uniform spherical silica aerogel granules having excellent workability and flowability can be provided.
