| titleOfInvention | The preparation method of fine cerium oxide |
| abstract | The invention discloses the preparation method of a kind of fine cerium oxide, the preparation saline solution containing cerium ion, then in this solution, add surfactant, in case of heating, allow above-mentioned solution contact with precipitant solution, generate precipitate, then filter, wash, be dried this precipitate, last calcination at 500 ~ 1000 DEG C, obtains D 50 It it is the fine cerium oxide of 0.1 ~ 2 μm.The present invention uses ammonium hydrogen carbonate and carbamide to do precipitant, and the advantage combining ammonium hydrogen carbonate and carbamide controls settling velocity with carbamide, by ammonium hydrogen carbonate regulation solution basicity provide precipitant, makes precipitation be smoothed out, and reduces reunion and obtain fine cerium oxide.Cerium oxide particle prepared by the present invention is thin, is evenly distributed, and is suitable for industrialized production, and the cost of the method is relatively low simultaneously. |
