Scandium Oxide Sc2O3 Powder CAS 12060-08-1

Scandium oxide (III) is an inorganic compound. The scandium oxide formula is Sc2O3. It is one of several oxides of rare earth elements with high melting points. It is used in preparing other scandium compounds and in high-temperature systems (because of its heat resistance and thermal shock properties), electronic ceramic, and glass components (as auxiliary materials). Properties: white solid.Cubic structure with rare earth sesquioxides.Density 3.864. Melting point 2403℃±20℃.Insoluble in water, soluble in hot acids.

Scandium oxide sc2o3 is one of the most important scandium products. Its physical and chemical properties are similar to those of rare earth oxides (such as La2O3, Y2O3, and Lu2O3), so the production methods used in the production are very similar. SC2O3 can generate scandium metal (Sc), products of different salts, and various scandium alloys. These scandium products have practical technical value and better economic effects. Because SC2O3 has some characteristics, it has been well used in aluminum alloy, electric light sources, lasers, catalysts, activators, ceramics aerospace, and so on, and its development prospect is very broad.

Scandium metal method: The purity of 99.99% scandium metal is heated to a high temperature in the air, which can be oxidized to produce scandium oxide. The advantage of this method is that the process is simple and easy to control, but it needs to use a large number of scandium metal raw materials, and the production cost is high.

Scandium hydroxide method: scandium hydroxide is added to hydrogen peroxide for reaction to obtain scandium oxide. The benefits of this method are the mild reaction conditions and easy operation. Still, it must use a large amount of scandium hydroxide raw materials, and the production cost is high.

Scandium oxychloride method: scandium oxychloride can be heated and decomposed to produce scandium oxide. The benefits of this method are the low reaction time and simple operation. Still, it must use a large amount of scandium oxychloride raw materials, and the production cost is high.

High-temperature decomposition method: scandium carbonate or scandium hydroxide is added to carbon and heated to high temperatures to produce scandium and carbon dioxide. Scandium is then reacted with chlorine gas to produce scandium chloride, scandium chloride is then reacted with hydrogen peroxide to produce scandium oxychloride, and finally, scandium oxychloride is decomposed by heating. The advantages of this method are quick reaction time and simple operation, but it needs to use a lot of carbon and chlorine raw materials, and the production cost is high.

Ion exchange method: using rare earth metal salts as raw materials, dissolving them in solvents, and then adding ion exchangers to react to produce rare earth ion exchange resin and ammonium chloride. The rare earth ion exchange resin is heated to a high temperature and burned to produce scandium oxide. The advantages of this method are low production cost and easy industrial production, but it needs to use a lot of rare earth metal salt raw materials.

Because of the unique physical and chemical properties of SC2O3, products have been applied and developed in many high-tech and industrial sectors since the 1980s.

Application in alloys

Currently consists of scandium and aluminum. Scandium aluminum alloy has a small density, high strength, hardness, plasticity, corrosion resistance, and thermal stability of strong advantages; therefore, in missiles, such as aerospace, aviation, automotive, and Marine structures for better application and gradually turned to civilian, such as sports (hockey and baseball handlebar) device, computer and following, It has the characteristics of high strength, high stiffness and lightweight.

Application of new electric light source materials

After pure SC2O3 is converted into SCI3 and NAI, a new third-generation electric light source material is made and processed into a scandium-sodium halogen lamp for illumination (each lamp about the material of SC2O3 ≥ 99% is 0.1mg ~ 10mg. The scandium spectral line in this lamp is blue under high voltage, and the sodium spectral line is yellow. The two colors cooperate and produce close to the light of the sun so that the light has the advantages of high luminosity, good light color, energy saving, long life, and strong fog-breaking force.

Applications of laser materials

Gadolinium gallium scandium garnet (GGSG) can be prepared by adding pure SC2O3 ≥ 99.9% gadolinium gallium garnet (GGG) in the form of Gd3SC2Ga3O12. Because it is made of the third generation of laser emitting power, the same volume of laser increased by 3.0 times, reached the high power and miniaturization of the laser device, improved the output power of laser oscillation, and improved the laser performance. When preparing a single crystal, each charge is 3kg ~ 5kg, and the raw material of SC2O3 ≥ 99.9% is about 1.0kg.

Applications in electronic materials

Pure SC2O3 can be used as an oxidizing cathode activator for the cathode gun of color TV picture tube with good effect. A 1mm thick Ba, Sr, and Ca oxide layer is sprayed on the upper end of the color tube cathode, and a 0.1mm thick SC2O3 is dispersed on it. In the oxide layer cathode, because of Mg, Sr, and Ba reaction, promote the reduction of Ba, the released electrons are more active and emit large current electrons, so that the fluorescence body luminescence, compared with the cathode without SC2O3 coating can increase the current density of 4 times, make the TV picture clearer so that the cathode life increased by three times. The amount of SC2O3 for each 21-inch imaging cathode is 0.1mg.

Storage Condition of Scandium Oxide Sc2O3 Powder :
The damp reunion will affect Sc2O3 powder dispersion performance and using effects, therefore, scandium oxide should be sealed in vacuum packing and stored in cool and dry room, the scandium oxide can not be exposure to air. In addition, the Sc2O3 powder should be avoided under stress.

Packing & Shipping of Scandium Oxide Sc2O3 Powder :
It is packed in double plastic bags inside, which can be filled with argon in a vacuum; it can be vacuumed and filled with argon for protection..
Scandium oxide Sc2O3 powder packing: vacuum packing, 100g, 500g or 1kg/bag, 25kg/barrel, or as your request.
Scandium oxide Sc2O3 powder shipping: could be shipped out by sea, by air, by express as soon as possible once payment receipt.
