Process for the manufacture of a powder of mixed metal oxides, and mixed metal oxide powders

摘要

Process for the manufacture of a powder of mixed metal oxides by cohydrolysis of metal alcoholates in the presence of an acidic organic compound and mixed metal oxide powders in which the molar relationships R1 and R2 of a metal oxide to the sum of the metal oxides in the powder and in a particle of the powder are such that <IMAGE> The process applies especially well to powders of zirconia doped with yttrium oxide or other oxides.
