Abstract
A method for producing an alkylsiloxane aerogel of the invention includes (a) a step of letting a reaction to produce a sol and a reaction to convert the sol to a gel take place in one step by adding a silicon compound whose molecules have a hydrolysable functional group and a nonhydrolysable functional group to an acidic aqueous solution containing a surfactant, and (b) a step of drying the gel produced in the step (a). In the step (b), the gel is dried at a temperature and a pressure below the critical point of a solvent used to dry the gel.
