Method for manufacturing silica aerogel and the silica aerogel manufactured using the method

摘要

The present invention relates to a method for producing a silica airgel, and more particularly, to a silica airgel produced by using a method for producing a silica airgel having high transparency and a method for producing the silica airgel. The method for producing a silica airgel according to a preferred embodiment of the present invention comprises the steps of hydrolyzing an alkaline silicate as a raw material to form a hydrosol; Condensing the silica sol to form a hydrogel having a SiO ₂ network structure; Aging the hydrogel; Silylating the aged hydrogel; And drying the silylated hydrogel at atmospheric pressure.
