Abstract

PURPOSE:To form a silica coating with excellent quality, by a method wherein an alkoxysilane is hydrolyzed in the presence of a catalyst in a solvent to prepare a coating solution and this solution is coated on a solid surface, and thereafter calcination is carried out. CONSTITUTION:An alkoxysilane, a solvent, water and a catalyst are mixed and reacted in an optional order to obtain a desired coating solution. As an alkoxysilane, for example, tetramethoxysilane or tetraethoxysilane is used alone or two or more of them are used together. As a solvent, alcohols, polyhydric alcohols or ethers thereof are used. Said catalyst is an acid catalyst selected from hydrochloric acid, sulfuric acid, nitric acid, carbonic acid and an H-type cation exchange resin or a metal catalyst selected from halide, nitrate or sulfate of a metal belonging to Group Ib, IIb, IV-VIII of the Periodic Table or an org. acid catalyst selected from org. acids and anhydrides thereof with pK or 4.0 or less. The reaction product is diluted with an org. solvent and filtered by a filter with a pore size of 0.2-10mu to obtain a coating solution.
