ABSTRACT:
A powder composition of ceric oxide and a stabilizing non-noble metal oxide, such as zirconium oxide, mixed at the atomic level in complete solid solution. The powder is used to form washcoats for catalytic converters. The composition has high oxygen storage capacity and maintains an ultrafine crystallite size at high temperatures. The powder is formed by a spray pyrolysis process that includes atomizing a clear solution of cerium ions and ions of the non-noble metal into a fine mist that is passed rapidly through a furnace to form powder particles.
