Silica-titania films with a concave-convex surface were prepared from a mixture of polymerized tetraethoxysilane (TEOS) sol containing tetraisopropoxytitanate and polymerized methyltriethoxysilane (MTES) sol in a molar ratio MTES/TEOS of 6. Film hardness was dependent on the composition of the coating sol, heat treatment temperature and time. The film obtained by introduction of 4mol% TiO₂ to SiO₂ and by heat treatment at 620°C for 10min was hard to be usable in engineering practice. New-type water-repellent glasses were produced y using these SiO₂-TiO₂ films as an under layer combined with fluoroalkylsilane; the glasses showed an abrasion resistance for practical application as automotive windows.
