Title (DE) NANOPARTIKEL AUS ALUMINIUMOXID UND OXIDEN VON ELEMENTEN DER I. UND II. HAUPTGRUPPE DES PERIODENSYSTEMS SOWIE DEREN HERSTELLUNG
(EN) NANOPARTICLES OF ALUMINA AND OXIDES OF ELEMENTS OF MAIN GROUPS I AND II OF THE PERIODIC TABLE, AND THEIR PREPARATION
(FR) NANOPARTICULES COMPOSEES D'OXYDE D'ALUMINIUM ET D'OXYDES D'ELEMENTS DU PREMIER ET DU DEUXIEME GROUPE PRINCIPAL DU TABLEAU PERIODIQUE ET FABRICATION
Abstract:
(DE) Es werden Nanopartikel beansprucht bestehend aus 50 - 99,99 Gew.-% Aluminiumoxid und 0,01 - 50 Gew.-% Metalloxid von Elementen der I. oder II. Hauptgruppe des Periodensystems. Diese Nanopartikel werden erhalten durch Eintrocknen einer Suspension aus Aluminiumchlorohydrat, Oxidbildner und gegebenenfalls Kristallisationskeimen, anschließende Kalzinierung und Zerkleinerung der dabei erhaltenen Agglomerate.
(EN) Nanoparticles are claimed which consist of 50% - 99.99% by weight alumina and 0.01% - 50% by weight metal oxide of elements of main group I and II of the Periodic Table. These nanoparticles are obtained by drying a suspension of aluminium chlorohydrate, oxide formers and, if desired, crystallization nuclei, followed by calcining and comminution of the resultant agglomerates.
(FR) L'invention concerne des nanoparticules composées de 50 à 99,99 % en poids d'oxyde d'aluminium et de 0,01 à 50 % en poids d'oxydes métalliques d'éléments du premier ou du deuxième groupe principal du tableau périodique. Ces nanoparticules sont fabriquées par séchage d'une suspension de chlorhydrate d'aluminium, de formeurs d'oxydes et éventuellement de germes cristallins, calcination consécutive et broyage des agglomérats obtenus.
