摘要： There is provided a process for producing an aerogel which comprises lowering a pH of a water glass solution to obtain a sol, gelling the sol to obtain a hydrogel, replacing water in the gel with an organic solvent, reacting the gel with a hydrophobilizing agent having hydrophobic groups as well as functional groups reactive with silanol groups in liquid phase, followed by supercritically drying; or hydrophobilizing and supercritically drying the resultant gel at the same time. Preferably, the hydrogel is prepared by ion exchanging alkali metals in the water glass solution using an ion exchange resin to obtain a sol which is subjected to suspension polymerization.

摘要： A hydrophobic aerogel having excellent transparency is formed by the following process of the present invention. That is, a first gel having a SiO₂ skeleton structure is prepared by hydrolysis and condensation of an alkoxysilane compound in the presence of a solvent. The solvent contained in the first gel is replaced at least partially with a medium to form a second gel. The second gel is reacted with a hydrophobic agent having hydrophobic groups as well as functional groups reactive with silanol groups under a supercritical condition of the medium to form a hydrophobic gel. The medium contained in the hydrophobic aerogel is removed by a supercritical drying method, so that the hydrophobic aerogel having improved transparency and an extremely fine porous structure is obtained.
