| titleOfInvention | Micron-order high-density erbium oxide microsphere and preparation method thereof |
| abstract | The invention provides a micron-order high-density erbium oxide microsphere. The particle size of the microsphere is 50-150mu m, and the density of the microsphere is more than or equal to 88 percent of theoretical density of erbium oxide powder. A preparation method of the micron-order high-density erbium oxide microsphere comprises the following steps: 1, performing ball-milling on a premixed solution and the erbium oxide powder until the erbium oxide powder is uniformly dispersed in the premixed solution, and adding an aqueous solution of ammonium persulfate, thus obtaining slurry of which the solid-phase content is 50-60 percent; 2, (1) uniformly mixing tween80 and an oil phase to form a first mixed solution, adding the slurry into the first mixed solution, and stirring to obtain an emulsion; (2) uniformly mixing tetramethyl ethylenediamine, span80 and an oil phase to form a second mixed solution, and adding the emulsion into the second mixed solution through a burette; and (3) cleaning the cured microsphere obtained in the step (2), and drying to obtain an erbium oxide microsphere biscuit; and 3, batching the erbium oxide microsphere biscuit, and keeping the temperature to be 1890-1910 DEG C for 170-190 minutes under inert gas shielding, thus obtaining the micron-order high-density erbium oxide microsphere. |
