METHOD OF PREPARING LAYERS OF OXIDES OF METALLIC ELEMENTS

摘要

The invention relates to a method of preparing a metallic element oxide layer on a substrate. The inventive method comprises the following successive steps consisting in: a) dispersing a metallic element oxide powder in a liquid medium which contains a dispersion solvent and a dispersant, but which does not contain a plasticiser nor a binder, such as to produce a suspension A of the powder in the liquid medium; b) adding a solution of at least one polymer in a solvent to suspension A, such as to produce a suspension B; c) depositing suspension B on the substrate using a dip-coating method, such as to produce a raw layer; d) drying the raw layer obtained in step c; and e) calcining the dried layer obtained in step d.
