| titleOfInvention | Method for producing rare earth oxide powder |
| abstract | The present invention provides a method for producing a submicron-sized rare earth oxide powder having no aggregation and excellent monodispersibility. An anionic surfactant containing a salt of a saturated or unsaturated fatty acid having 6 to 20 carbon atoms is added to an aqueous solution containing a rare earth metal ion, and the aqueous solution to which the anionic surfactant is added is hydrophobic. A water-in-oil (W / O) emulsion solution by mixing a water-soluble organic solvent, a step of adding a precipitant to the emulsion solution to precipitate a rare earth oxide precursor, and the rare earth oxide Separating the precursor precipitate from the solution, drying and then firing to obtain a rare earth oxide powder having an average particle size of 10 nm to 1 μm.
