A process to produce mixed metal oxides and metal oxide compounds. The process includes evaporating a feed solution that contains at least two metal salts to form an intermediate. The evaporation is conducted at a temperature above the boiling point of the feed solution but below the temperature where there is significant crystal growth or below the calcination temperature of the intermediate. The intermediate is calcined, optionally in the presence of an oxidizing agent, to form the desired oxides. The calcined material can be milled and dispersed to yield individual particles of controllable size and narrow size distribution.

L'invention concerne un procédé de préparation d'oxydes métalliques et de composés d'oxydes métalliques mélangés. Ce procédé consiste à faire évaporer une solution d'alimentation contenant au moins deux sels métalliques pour obtenir un produit intermédiaire. L'évaporation est réalisée à une température supérieure au point d'ébullition de la solution d'alimentation mais inférieure à la température à laquelle se produit une importante croissance de cristaux, ou encore, inférieure à la température de calcination du produit intermédiaire. Le produit intermédiaire est calciné, éventuellement en présence d'un agent oxydant, pour former les oxydes souhaités. Le matériau calciné peut être broyé et dispersé pour obtenir des particules individuelles de taille maîtrisée et à distribution granulométrique étroite.
