Method for preparing a material on a substrate by sol-gel means

The invention relates to a method for preparing a material based on metal element(s) oxide(s) on a substrate, comprising the following successive steps: a) depositing, by liquid means, on at least one face of this substrate, at least one layer of a sol-gel precursor solution of the constituent metal...

Beschreibung
Zusammenfassung:	The invention relates to a method for preparing a material based on metal element(s) oxide(s) on a substrate, comprising the following successive steps: a) depositing, by liquid means, on at least one face of this substrate, at least one layer of a sol-gel precursor solution of the constituent metal element(s) oxide(s) of said material; b) depositing, by liquid means, on said layer deposited in a), at least one layer of a dispersion comprising a powder of metal element(s) oxide(s) and a sol-gel solution identical to or different from that used in step a), said solution being a precursor of the constituent metal element(s) oxide(s) of said material and the powder consisting of constituent metal element(s) oxide(s) of said material; c) heat treating said layers deposited in a) and b) in order to transform them into said material.
