COLLOIDAL DISPERSION OF A CERIUM COMPOUND OR A CERIUM COMPOUND AND AT LEAST ONE OTHER ELEMENT SELECTED AMONG RARE EARTHS AND TRANSITION METALS, INCLUDING AN AMINO ACID

摘要

The invention concerns a colloidal dispersion of a cerium compound or of a cerium compound and at least another element selected among titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc, aluminum, gallium, zirconium and rare earths other than cerium. The invention is characterised in that it comprises an amino acid, said acid being at least bound to particles constituting the dispersion. Said dispersion can be used on a substrate as anticorrosive agent, for preparing polymer films, in a cosmetic composition, in catalysis particularly for motor vehicle post-combustion catalysis, for lubrication and in ceramics.
