1455148 Oxide coatings GLAVERBELMECANIVER 18 Dec 1973 [21 Dec 1972] 58483/73 Headings C1A and C1N A method of forming a coating on a substrate in which the coating comprises an oxide or oxides of one or more metals and/or of silicon, wherein a solution comprising at least one metal compound and/or a silicon compound is applied to the substrate and converted by heat to form a coating, the solution being of one or more metallic salts and or a silicon salt of acetates, halides or nitrates in an aprotic solvent having a dielectric constant greater than 15 and a dipole moment greater than 3D. The solvent may be dimethylformamide, dimethylacetamide, tetramethyl urea, dimethylsulphoxide, acetonitrile, nitrobenzene, ethylene carbonate, tetramethylene sulphane or hexamethylphosphoramide and may also contain acetylacetane. The solution may comprise one or more acetates, halides or nitrates of Mg, Zr, V, Cr, W, Mn, Fe, Co, Ni, Cu, Zn, Cd, In, Sn, Pb, Bi, Th, Si, or also, Au, Ti, Ce, Mo, Sb, Al, As, Rh. The solution may be applied to a substrate which is vitreous or partly vitreous and the coating may be transparent to light. |
