Beschreibung
Zusammenfassung:	The subject matter of the invention is a method for producing composites comprising aluminum oxide and cerium/zirconium mixed oxides, hereinafter referred to briefly as Al/Ce/Zr oxide composite(s) using boehmite and soluble cerium/zirconium salts. Al/Ce/Zr oxide composites produced in this way have an increased thermal stability. L'invention concerne un procédé de production de composites contenant de l'oxyde d'aluminium et des oxydes mixtes de cérium/zirconium, ci-après dénommés composite(s) d'oxyde Al/Ce/Zr, en utilisant de la boehmite et des sels de cérium/zirconium solubles. Les composites d'oxyde Al/Ce/Zr ainsi produits présentent une stabilité thermique élevée.
