| titleOfInvention | A kind of preparation method of flake cerium carbonate |
| abstract | The invention discloses a kind of preparation method of flake cerium carbonate, concentration is equipped with first for the trivalent cerium ion solution A and concentration of 0.58mol/L ~ 0.87mol/L are the ammonium bicarbonate soln B of 1.27mol/L ~ 1.9mol/L so that the mol ratio of trivalent cerium ion and ammonium hydrogen carbonate in solution is 2:7, the ammonium bicarbonate soln B of 1% volume is first added in reaction vessel, trivalent cerium ion solution A and ammonium bicarbonate soln B are added in reaction vessel simultaneously with slow speed respectively afterwards, the precipitation for generating is washed with deionized water C, dried after finally washing suitable cerous carbonate precipitation suction filtration.Energy consumption is small, supplies consumption is relatively low, has the advantages that the requirement of material impurity level is relatively low, later stage treatment is simple, application value is high. |
