Abstract
A method for producing a silica aerogel, the method including preparing a reactant by adding a basic catalyst to a first silica precursor solution, performing primary gelation in which the reactant is stirred to form a gel precursor, introducing a second silica precursor solution to a fiber, and performing a secondary gelation in which the gel precursor is introduced to the fiber to which the second silica precursor solution was introduced to form a silica aerogel.
