Production method and application of yttrium oxide Y2O3

Overview of Yttrium Oxide Y2O3 Powder

Yttrium(III) oxide, also known as yttrium oxide, has a chemical formula of Y2O3 and a molecular weight of 225.81.

It is a white, slightly yellow crystalline powder, insoluble in water and alkali, but soluble in acid and alcohol. When exposed to the air, it is easy to absorb carbon dioxide and water and deteriorate. Used for making incandescent gas lampshades, color TV phosphors, magnetic material additives, and also used in the atomic energy industry.

production method

1. The mixed rare earth obtained by decomposing brown yttrium niobium ore by extraction method contains Y2O350% and CeO2 about 4%. The rare earth nitrate solution after removing cerium is fed, and the N2O3-LiNO3 system is used to extract and group to obtain yttrium-rich rare earth. The N2O3-heavy solvent-NH4SCN system extracts and purifies yttrium, and the raffinate after grouping is yttrium-rich rare earth, which is directly concentrated, filtered and fired to prepare yttrium oxide. The chemical equation is:

Y2(C2O4)3→Y2O3+3CO2+3CO

2. Nano particles of metal yttrium are prepared by the uniform reduction method of alkali metal according to the following equation. The obtained by-product was removed by washing with carbonic acid at room temperature. In the washing process, the metal yttrium is oxidized to Y2O3, and the product is washed and separated by a centrifuge (15500×G).

Raw material: Anhydrous YCl3, 99.99% pure, no further purification is required. Crown ether (15-crown-5, 98%) needs to be dried and further purified by vacuum distillation. THF (99.94% HPLC grade reagent) is stirred with KNa alloy until a stable blue solution is obtained. The reaction device is placed in a dry box filled with N2 (<1×10-6H2O, O2), the solvent transfer uses vacuum line (133.322×10-6Pa) technology, and the bauxite combustion boat is used for annealing in a tube furnace in an atmospheric environment. .

3. At a temperature higher than 410°C, heat and decompose yttrium oxalate in a thermobalance at a heating rate of 5.4°C per minute.

4. Solvent extraction method of naphthenic acid-hydrochloric acid system. Using concentrate rich in yttrium rare earth (about 370% Y2O) as raw material, prepare 0.8mol/L REC13, pH=2～3 rare earth chloride solution as feed liquid, adopt naphthenic acid-mixed alcohol-kerosene solution Extract and purify yttrium from hydrochloric acid medium.

Application of Yttrium Oxide Y2O3 Powder

1. Used in the manufacture of various ceramics, optical glass, phosphors, laser materials and refractory materials, as a catalyst for the synthesis of ethane from carbon monoxide and hydrogen;

2. Used as an additive material for phosphors and magnetic materials;

3. Mainly used in the manufacture of single crystal, yttrium iron garnet, yttrium aluminum neodymium garnet and other composite oxides. These composite oxides can be used as magnetic materials for microwaves and important materials for military communications engineering due to their good high-frequency performance. It can also be used as high-temperature transparent glass made of advanced optical glass additives, ceramic material additives, rare earth phosphors for X-ray intensifying screens, high-brightness phosphors for large-screen TVs and other picture tube coatings. In addition, it is also used in the manufacture of film capacitors and special refractory materials, as well as high-pressure mercury lamps, lasers, storage components, and other foam magnetic materials;

4. Used for making incandescent gas lampshades, color TV phosphors, magnetic material additives, and also used in the atomic energy industry.

Widely used in various fluorescent materials, high-quality refractory materials, artificial gem laser crystals, superconducting materials and many cutting-edge applications in the electronics industry
