Zirconium and yttrium oxide-based composition with a specific surface area of at least 12 m?2¿/g following calcination at 1000 ·C for 10 hours. This composition is obtained via a method wherein a mixture of zirconium and yttrium compounds is precipitated with a base; the resulting precipitate-containing medium is heated; a compound selected from anionic surfactants, non-ionic surfactants, polyethylene glycols, carboxylic acids and the salts thereof and carboxymethylated fatty alcohol ethoxylate-type surfactants is then added to said precipitate, and, finally, the precipitate is calcined. Said composition can be used as a catalyst.

La composition de l'invention est à base d'oxydes de zirconium et d'yttrium et elle présente une surface spécifique d'au moins 12 m2/g après calcination à 1000~C pendant 10 heures. Cette composition est obtenue par un procédé dans lequel on fait précipiter avec une base un mélange des composés de zirconium et d'yttrium; on chauffe le milieu obtenu qui contient un précipité; puis on ajoute à ce précipité un composé choisi parmi les tensioactifs anioniques, les tensioactifs non ioniques, les polyéthylène-glycols, les acides carboxyliques et leurs sels et les tensioactifs du type éthoxylats d'alcools gras carboxyméthylés et on calcine enfin le précipité. La composition peut être utilisée comme catalyseur.
