Overview of Scandium Oxide Sc2O3 Powder

Scandium oxide is an inorganic compound with the molecular formula SC2O3. It is one of several oxides of high melting point rare earth elements. It is used to prepare other scandium compounds as well as high-temperature systems (due to its heat resistance and thermal shock characteristics), electronic ceramics, and glass components (as auxiliary materials). The chemical formula of scandium oxide is SC2O3. Properties: white solid. Cubic structure, rare earth sesquioxide. The density is 3.864. The melting point is 2403 ℃ ± 20 ℃. Insoluble in water, soluble in hot acid. It is made by the thermal decomposition of scandium salt. It can be used as an evaporation material for semiconductor coating. Make variable-wavelength solid-state lasers, high-definition TV electron guns, metal halide lamps, etc.

Scandium oxide (Sc2O3) is one of the more important products in scandium products. Its physical and chemical properties are similar to rare earth oxides (such as La2O3, Y2O3, and Lu2O3, etc.), so the production methods used in production are very similar. Sc2O3 can generate metal scandium (Sc), products of different salts (ScCl3, ScF3, ScI3, Sc2(C2O4)3, etc.), and a variety of scandium alloys (Al-Sc, Al-Zr-Sc series). These scandium products have practical technical value and good economic effects. Because Sc2O3 has some characteristics, it has been used in aluminum alloys, electric light sources, lasers, catalysts, activators, ceramics, and aerospace, etc., and its development prospects are very broad.

In the 1970s, my country began to develop Sc2O3 products, and kilogram-level products entered the market. In the 1980s, my country's Sc2O3 production reached a climax, with the output reaching the level of 100 kilograms or more, and it was mainly exported to Japan and the United States. Since the 1990s, Russia has produced a large number of Sc2O3 products and sold them to the international market at low prices, which has severely impacted the production of scandium oxide in China, making Sc2O3 production at a low level, and many production lines have been discontinued, making China's production capacity and output in a state of shrinking. However, in recent years, the development of Sc-Al alloy and electric light source materials in China has promoted the development of Sc2O3 industrial production. my country's scandium resources are very rich. According to reports, the current industrial reserves of scandium in the world are about 2 million tons, and my country has about 600,000 to 650,000 tons, accounting for about 30% of the world's total content.

Properties of Scandium Oxide Sc2O3 Powder

Scandium oxide is a white solid with a cubic rare earth arsenic trioxide structure. Scandium oxide is insoluble in water but soluble in hot acid.

How is scandium oxide Sc2O3 powder produced? 

Scandium oxide is the main form of extraction produced by the mining industry. Rich minerals, such as mica th(Sc, Y) 2 (Si2O7) and Kolbeckite ScPO4·2H2O, are rare, but there are also traces of sodium in many other minerals. Therefore, scandium oxide is mainly produced as a by-product of the extraction of other elements.

Application of Scandium Oxide Sc2O3 Powder

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

Application of Scandium Oxide Sc2O3 Powder in Alloy

At present, scandium aluminum alloy composed of consistency, and aluminum has the advantages of low density, high strength, hardness, plasticity, corrosion resistance, and strong thermal stability. Therefore, it is better used in missiles, such as aerospace, aviation, automobile, and ship structures. Good applications are gradually turning to civilian use, such as sports (hockey and baseball handlebars) equipment, computers, and their subsequent equipment, which have the characteristics of high strength, high rigidity, and lightness.

Application of Scandium Oxide Sc2O3 Powder New Type Electric Light Source Materials

After the pure SC2O3 is converted into SCI3 and NAI, a new type of third-generation electric light source material is made and processed into a sodium halide-sodium lamp for lighting (each lamp with SC2O3≥99% material is 0.1mg~10mg. Under the action of high pressure, the scan spectrum line is blue and the sodium spectrum line is yellow. The two colors cooperate with each other to produce light close to the sun, so it has a high luminosity, good light color, energy saving, long life, and strong defogging power.

Application of Scandium Oxide Sc2O3 Powder Laser Material

Adding gallium garnet (GGSG) can be prepared by adding ≥99.9% pure gallium garnet (GGG) in the form of Gd3SC2Ga3O12. The emission power of the third-generation laser made by it is 3.0 times higher than that of a laser of the same volume, and it has reached a high-power and miniaturized laser device, which has increased the output power of the laser oscillation and improved the performance of the laser. When preparing a single crystal, the charge is 3kg~5kg each time, and the raw material of SC2O3≥99.9% is about 1.0kg.

Application of Scandium Oxide Sc2O3 Powder Electronic Materials

Pure SC2O3 can be used as an oxidizing cathode activator for cathode guns of color picture tubes. A layer of Ba, Sr, and Ca oxides with a thickness of 1 mm is sprayed on the upper end of the cathode of the color tube, and a layer of SC2O3 with a thickness of 0.1 mm is dispersed on it. In the oxide layer cathode, Mg, Sr, and Ba react to promote the reduction of Ba, and the released electrons are more active, emitting high current electrons, making the phosphor emit light. Compared with the cathode without SC2O3 coating, the current density can be increased. 4 times, the TV screen is clearer, and the cathode life is increased by 3 times. The amount of SC2O3 per 21-inch imaging cathode is 0.1 mg.
