Title:
CERIA-ZIRCONIA-MIXED OXIDE PARTICLES AND PROCESS FOR THEIR PRODUCTION BY PYROLYSIS OF DISPERSIONS
Document Type and Number:
WIPO Patent Application WO/2014/203179
Kind Code:
A3
Abstract:
A process for the production of mixed oxide particles comprising: (1) providing a dispersion comprising a disperse phase and a continuous phase, wherein the disperse phase comprises 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; (2) forming an aerosol of the dispersion provided in step (1); and (3) pyrolyzing the aerosol of step (2) to obtain mixed oxide particles, as well as to mixed oxide particles obtainable from flame spray pyrolysis, and preferably obtainable by the process and to its use.
