Abstract

Provided is a method for producing, at low cost, a dense and porous silica glass precursor from which silica glass can be easily formed in a complex shape at low cost, and which can also be utilized in an absorbent or the like utilizing porousness thereof as another use. A silica glass precursor production method includes: a stirring step of stirring a silica solution containing silica particles and a pH adjuster to produce a dispersion solution; a mixing step of mixing, into the dispersion solution, an initiator solution containing a photopolymerization initiator and an acrylic monomer having a hydroxyl group at one end of an alkyl chain optionally substituted by a substituent, and an acryloyl group optionally substituted by an alkyl group at the other end of the alkyl chain, to produce a mixed solution; an irradiation step of irradiating the mixed solution with light to form a silica-containing molded body; and a solidification step of producing a mesoporous silica glass precursor formed by solidifying the silica-containing molded body by annealing and/or drying.
