PCT No. PCT/EP95/01844 Sec. 371 Date Jan. 10, 1997 Sec. 102(e) Date Jan. 10, 1997 PCT Filed May 16, 1995 PCT Pub. No. WO95/31413 PCT Pub. Date Nov. 23, 1995Structured inorganic layers are produced by optionally mixing a composition which is obtainable by hydrolysis and polycondensation of (A) at least one hydrolyzable silane of general formula (I) SiX4 (I) wherein the radicals X are identical or different and represent hydrolyzable groups or hydroxyl groups, or an oligomer derived therefrom, and (B) at least one organosilane of general formula (II) R1aR2bSiX(4-a-b)(II) wherein R1 is a non-hydrolyzable group, R2 represents a radical carrying a functional group, X has the meaning specified above, and a and b are 0, 1, 2 or 3, the sum (a+b) being 1, 2 or 3, or an oligomer derived therefrom, in a ratio of amount of substance (A):(B) of 5-50:50-95, as well as (C) optionally, one or more compounds of glass- or ceramic forming elements, with a fine-scaled filler, applying the resulting composition onto a substrate, structuring the applied composition and thermally densifying the structured coating to form a structured layer.
