METHOD FOR PRODUCING SILICA AEROGEL |
摘要 |
A method for producing silica aerogel according to the present invention includes: a solation step of generating a sol by adding monoalkyltrialkoxysilane to an acidic aqueous solution containing silicic acid; and a gelation step of generating a wet gel by gelating the sol. Moreover, the production method includes a drying step of removing a solvent, which is contained in the wet gel, from the wet gel by drying the wet gel at less than a critical temperature of the solvent and at less than a critical pressure of the solvent. Then, the monoalkyltrialkoxysilane is added to the acidic aqueous solution so that an amount of silicon in the monoalkyltrialkoxysilane becomes 1 mol part or more with respect to 1 mol part of an amount of silicon in the acidic aqueous solution containing the silicic acid. |
