| titleOfInvention | Method for producing rare earth oxide powder |
| abstract | (57) [Summary] (Modified) [Structure] Step 1) Add an alkaline carbonate in excess of the equivalent amount required to precipitate the rare earth element as a carbonate to the rare earth element mineral acid salt aqueous solution. After the salt is precipitated, step 2) the precipitate-containing slurry is heated and aged, and step 3) a rare earth element mineral acid salt aqueous solution is further added to the slurry and aged again by heating, and then step 4) filtration and washing with water, Dry, A method for producing a rare earth element oxide powder, which comprises firing. According to the present invention, it is possible to produce a rare earth element oxide powder which is useful as a raw material for a rare earth element sintered body and a sintering aid for ceramics and has good agglomeration and good dispersibility in a simple process at low cost. |
