Title
(EN) METHOD FOR OBTAINING ALUMINIUM OXIDE WITH ALLOYING ADDITIONS
(FR) PROCEDE D'OBTENTION D'OXYDE D'ALUMINIUM A L'AIDE D'ADDITIONS D'ALLIAGE
Abstract
(EN)
A method for obtaining the aluminium oxide with allowing additions consists in boiling a low-water aluminium hydroxide and then mixing it with an aqueous solution of a metal oxide. The sediment is extracted from the obtained mass and is dried at a temperature of 150-300°C. The dried sediment is desaggregated sediment is calcinated.
(FR)
Un procédé d'obtention d'oxyde d'aluminium à l'aide d'additions d'alliage, consiste à porter à ébullition un hydroxyde d'aluminium à faible teneur en eau, puis à le mélanger à une solution aqueuse d'un oxyde métallique. On extrait le sédiment de la masse obtenue, puis on le sèche à une température comprise entre 150°C et 300°C. On procède ensuite à la désagrégation ainsi qu'à la calcination du sédiment séché.
