Abstract

PURPOSE: To obtain a thin film of silica glass having transparency and uniformity, by forming a solution prepared by hydrolyzing a silicon alkoxide into a thin film in a free space, followed by heating the thin film.
CONSTITUTION: A silicon alkoxide is hydrolyzed in the presence of water, an acid, and a solvent to give a viscous solution. The solution is formed into a thin film in a free space and the thin film is heated to prepare a thin film of silica glass. For example, drawing the solution from a slit, extruding it from the slit, and immersing a ring in the solution and pulling it up may be preferably cited as the method forming the thin film in the free space. The solvent is used to prevent the phase separation between the silicon alkoxide and water and nonuniform gelation caused by the abrupt reaction of the silicon alkoxide and water, and its amount is fixed to match the purpose.
