PROCESS FOR OBTAINING A CERIC OXIDE |
| 摘要 |
<p>The ceric oxides of the invention have a high specific surface of at least 85 m<2>/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 cm<3>/g and pores with a mean diameter greater than 50 ANGSTROM . …<??>They can be employed in the field of catalysis.</p> |
