Title:
エアロゲルとその製造方法
Document Type and Number:
Japanese Patent JP6405540
Kind Code:
B2
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 m 2 /g to 475 m 2 /g can be prepared.
