Application of Scandium Oxide Sc2O3 Powder in Electronic Materials

Overview of Scandium Oxide Sc2O3

The chemical formula of scandium oxide is Sc2O3. Properties: white solid. It has a cubic structure of 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 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 over 100 kilograms, 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, causing the production of Sc2O3 to be at a trough, and many production lines have been discontinued, making China's production capacity and output 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.

Application of Scandium Oxide Sc2O3 Products

Due to the unique physical and chemical properties of Sc2O3 products, since the 1980s, it has obtained better application development in many high-tech and industrial sectors. At present, the application status of Sc2O3 in alloys, electric light sources, catalysts, activators and ceramics in my country and the world is described later.

Application of Scandium Oxide Sc2O3 Products in Electronic Materials

Pure Sc2O3 can be used as an oxidizing cathode activator for the cathode electron gun of a color television picture tube, and the effect is better. Spray a layer of Ba, Sr, and Ca oxide layer with a thickness of one millimeter on the upper end of the cathode of the color tube, and then diffuse a layer of Sc2O3 with a thickness of 0.1 millimeter on it. In the oxide layer cathode, Mg, Sr and Ba react to promote the reduction of Ba. The released electrons are more active and emit large current electrons to make the phosphor emit light. Compared with the cathode without Sc2O3 coating, the current density can be increased by 4 times. The TV picture is clearer, and the life of the cathode is increased by 3 times. The amount of Sc2O3 used for each 21-inch developing cathode is 0.1mg. At present, this cathode has been used in some countries in the world. For example, it is used more in Japan, which can improve market competitiveness and promote the sales of TV sets.

Application of Scandium Oxide Sc2O3 Products in Alloys

At present, the aluminum-scandium alloy (Al-Sc) made of scandium and aluminum has low density (Sc is 3.0g/cm3, Al is 2.7g/cm3, high strength, high hardness, good plasticity, corrosion resistance and thermal stability. Strong and other advantages, therefore, better applications in the structural parts of missiles, aerospace, aviation, automobiles and ships, etc., and gradually turn to civilian use, such as sports devices (hockey and baseball handles), computer and mobile phone cases, etc. It has the characteristics of high strength, high rigidity and light weight, which is of great practical value.

Scandium in the alloy mainly plays the role of modifying and refining the grain, so that the new phase of Al3Sc type is formed and presents the characteristics of excellent performance. Al-Sc alloys have formed a series of alloy series. For example, Russia has reached 17 Al-Sc series, and my country also has several alloys (such as Al-Mg-Sc-Zr and Al-Zn-Mg-Sc alloys). The characteristics of this type of alloy cannot be replaced by other materials, so from the perspective of development, its application development and potential are great, and it is expected to become a major application in the future. For example, Russia has been industrialized and used for light structural parts to develop rapidly, and my country is also accelerating the development and application, especially in aerospace and aviation.

Application of Scandium Oxide Sc2O3 Products in New Type Electric Light Source Materials

The pure Sc2O3 is converted into ScI3 and then combined with NaI to make a new type of third-generation electric light source material, and processed into a scandium-sodium halogen lamp for lighting (each lamp uses about 0.1mg-10mg of Sc2O3≥99% material. This is the case. Under the action of high-voltage electricity, the scandium spectrum is blue and the sodium spectrum is yellow. The two colors cooperate to produce light close to sunlight, which makes the light have high luminosity, good light color, energy saving, and longevity. Long and strong fog breaking power and other advantages.

Application of Scandium Oxide Sc2O3 Products in Laser Materials

Gadolinium Gallium Garnet (GGG) can be made into Gadolinium Gallium Scandium Garnet (GGSG) by adding pure Sc2O3≥99.9% to Gd3Sc2Ga3O12. The third-generation laser made of it has an emission power that is 3.0 times higher than that of a laser with the same volume. It has reached a high-power and miniaturized laser device, increased the output power of the laser oscillation, and improved the performance of the laser. When preparing single crystals, each charge is 3kg～5kg, adding Sc2O3≥99.9% raw material is about 1.0kg. At present, the application of this kind of laser in military technology is becoming more and more extensive, and it is gradually being promoted to the civilian industry. From the perspective of development, there will be greater potential for military and civilian use in the future.
