Ceric oxides exhibiting novel morphological characteristics, and process for obtaining them

摘要

The ceric oxides of the invention have a high specific surface of at least 85 m2/g after calcination between 350 and 550 DEG C and are characterised by the fact that they have a pore volume of at least 0.15 cm3/g and pores with a mean diameter greater than 50 ANGSTROM . …??They can be employed in the field of catalysis.
