Composition containing ceric oxide, its preparation and use |
| abstract |
The invention relates to compositions based on ceric oxide, whose specific surface has been stabilised by addition of silicon. These compositions have, after calcination at 800 DEG C for 6 hours, a specific surface of at least 40 m<2>/g and, after calcination at 1000 DEG C for 6 hours, a specific surface of at least 20 m<2>/g. Their silicon content is preferably less than 1 % by weight. They have a remarkably low crystallite size, even at high temperatures. They are obtained according to one of the processes consisting in autoclaving a cerium hydroxynitrate suspension in basic medium and in the presence of a silicon compound, in recovering the product obtained and in then calcining it. The compositions can be used as catalysts and/or as catalyst supports. |
