  • Ceric oxide particulates having a stable specific surface and a process for their preparation
    Patent number: 4940685
    Abstract: A ceric oxide composition, the specific surface of which remains essentially stable at elevated temperatures and which is thus well adopted for purposes of catalysis, is comprised of a plurality of solid, porous, finely divided ceric oxide particulates, said ceric oxide particulates advantageously having an effective amount of at least one oxide of another metallic element A intimately dispersed therein as to essentially prevent the coalescence of the micropores thereof.
