Abstract: In a method for manufacturing an aerogel, an acid is added to a first aqueous high-molar-ratio silicate solution that includes silica particles having a mean particle diameter of from 1 nm to 10 nm and that is alkaline, to produce a gel. The gel is subjected to a dehydration condensation to obtain a hydrogel. The hydrogel is converted into a hydrophobized gel. Then, the hydrophobized gel is dried. According to the method, an aerogel having a pore volume of from 3.00 cc/g to 10 cc/g, a mean pore diameter of from 10 nm to 68 nm, and a specific surface area of from 200 m2/g to 475 m2/g can be prepared.

Abstract: An alkoxysilane containing reactive organic functional groups is prepared as one of raw materials. The reactive organic functional groups are caused to react to bond with each other in advance so as to form an oligomer. The oligomer is swollen in an alkoxysilane of an identical or different kind, so that a sol solution is prepared and the sol solution is cured through a sol-gel reaction.
