YtterbiumoxideREO - Preparation Method
Open Data Verified Data
extraction method: the mixed rare earth obtained by decomposing brown yttrium niobium ore contains Y203 50% and Ceo2 about 4%. The rare earth nitrate solution after cerium removal is fed, and the rare earth rich in yttrium is extracted and grouped by N263-L1N03 system, after Acid dissolution, the pure yttrium is extracted with N263-heavy solvent-NH4 SCN system. The raffinate is yttrium-rich rare earth, and thulium, ytterbium and strontium heavy rare earth enter the organic phase, then, it is extracted by N263-heavy solvent to group thulium, back-extracted with hydrochloric acid to make thulium and ytterbium enter the aqueous phase, separated by oxalic acid precipitation, filtered and burned to obtain ytterbium oxide.

| overview | ytterbium oxide chemical formula Yb2O3. Molecular weight 394.08. The pure product is a colorless powder, light brown or yellow when containing thulium oxide. Micro hygroscopicity, absorbing carbon dioxide from the air. Specific gravity 9.2. Melting point 2,346 ℃. It is the weakest alkaline in the yttrium group except lutetium oxide. Insoluble in water and cold acid, soluble in hot dilute acid. With the development of science and technology, large-particle ytterbium oxide is used in coatings, sputtering, vacuum coating and other fields. For example, ytterbium oxide is coated on the surface of diamond, which makes the infrared transmittance sewing increase the 12% and has higher The demand for rain corrosion resistance, the demand for large-particle ytterbium oxide is increasing. As the large-particle ytterbium oxide is used as a thermal spraying powder, the amount of fine particles that are overmelted will be reduced during thermal spraying, the fine particles formed by small particles during thermal spraying adhere to and deposit on the inner wall of the nozzle of the thermal spraying device. The deposits formed by the fine particles fall off from the inner wall and are mixed into the thermal spraying coating to reduce the accumulation resistance of the thermal spraying coating. The direct preparation of ytterbium oxide powder particles that meet the requirements of thermal spraying can improve the density, accumulation resistance and wear resistance of the coating. |
| application | ytterbium oxide is used to make permanent magnet materials, glass, ceramic colorants, laser materials, thermal shielding coating materials, electronic materials, battery materials, biopharmaceutical, electronic industry and chemical research applications show superior performance. |
| Preparation | A preparation method for large particles of ytterbium oxide with uniform particles, good fluidity, morphology from flakes stacked into petals, and a central particle size D50 of 55-60 μm. Technical solution: Add ammonium bicarbonate, ammonia water with a concentration of 28% and deionized water to the reactor, the molar ratio of ammonium bicarbonate, ammonia water and deionized water is 1:1: 6.27, and the concentration is 1.75mol/L The ytterbium nitrate solution, the molar ratio of ammonium bicarbonate to ytterbium nitrate is 1: 0.078, to obtain a mixed solution of ammonium bicarbonate, ammonia water and ytterbium nitrate; add 30% hydrogen peroxide to the mixed solution, the molar ratio of ytterbium nitrate to hydrogen peroxide is 1: 4.6, the reaction starts to produce precipitation after 4 hours, and the precipitation is aged for 24-48 hours to obtain ytterbium carbonate precipitation. The precipitation is filtered and washed, and the burning temperature is 900-1200 ℃, and the heat is kept for 4 hours., The central particle size D50 is 55-60 μm, the particle distribution is uniform, the fluidity is good, and the morphology is stacked from flakes into petals. |
