摘要： Described is a process for the production of mixed oxide particles. The process comprises providing a mixture comprising a solvent, one or more precursor compounds of ceria, one or more precursor compounds of zirconia, and one or more precursor compounds of one or more rare earth oxides other than ceria and/or one or more precursor compounds of yttria; forming an aerosol of the mixture; and pyrolyzing the aerosol of to obtain mixed oxide particles. The content of the rare earth oxides other than ceria and/or of yttria in the mixed oxide particles is comprised in the range of from 0.1 to 4.9 wt.-% based on the total weight of the rare earth oxides, yttria, and zirconia contained in the mixed oxide particles. Also describes are mixed oxide particles obtained from flame spray pyrolysis and to their use as an oxygen storage component, a catalyst, and/or as a catalyst support.
