Abstract: PROBLEM TO BE SOLVED: To provide a layer on a substrate having high mechanical stability and free from cracks. SOLUTION: This layer is obtained by heat-treating an aqueous dispersion coated on a substrate where the dispersion contains a silicon-titanium mixed oxide powder produced by flame hydrolysis. The layer is formed by the steps of coating the dispersion containing a silicon-titanium mixed oxide powder and sintering the coating by a heat treatment. The layer can be applied to a material with extremely low expansion percentage. COPYRIGHT: (C)2003,JPO
