| titleOfInvention | Preparation method of large-particle lutetium oxide |
| abstract | The invention relates to a preparation method of large-particle lutetium oxide, belonging to a preparation technology of material. The method comprises the following steps of: preparing an ammonium bicarbonate solution with ammonium bicarbonate, ammonia water and deionized water, adding lutetium nitrate hydrate solution to the ammonium bicarbonate solution to obtain a mixed solution of ammonium bicarbonate, ammonia water and lutetium nitrate hydrate, adding hydrogen peroxide to the mixed solution, reacting for 6 hours to generate a lutetium carbonate hydrate precipitation, aging for 24-48 hours, filtering and washing the precipitation, keeping the firing temperature at 900-1200 DEG C for thermal insulation for 4 hours to obtain the large-particle gadolinium oxide product, which has the characteristics of uniform particle, favorable liquidity, and the morphology of which appears to be a petal piled by sheet and the central grain size D50 of which is 50-165 micrometers. |
