ABSTRACT:
The production of cerium oxides, zirconium oxides, (Ce,Zr)O.sub.2 mixed oxides and (Ce,Zr)O.sub.2 solid solutions having improved particle size distribution, surface area, oxygen storage capacity and pore volume by the addition of an additive, such as anionic surfactants, nonionic surfactants, polyethylene glycols, carboxylic acids, and carboxylate salts, during the formation of the oxides or precursors thereof.
