Beschreibung
Zusammenfassung:	A silica sol, a silica aerogel blanket using the same, and a method for manufacturing the same, wherein a hydrophobizing agent, a base catalyst, an organic solvent, and water are included in a catalyst composition when manufacturing the silica aerogel blanket, so that a wet aging step which is performed under high-temperature conditions and increases the amount of a solvent used, and a surface modification step which uses a large amount of an organic solvent and an expensive surface modifier, resulting in a process that is complex and long and thus inhibiting economic feasibility and productivity, can be omitted.
