Applications 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. Therefore, it has been well used in

the structural parts of missiles, aerospace, aviation, automobiles and ships, etc., and

gradually turned to civilian use, such as sports equipment (hockey and baseball sticks),

computers and mobile phone shells, etc. It has the characteristics of high strength, high

rigidity and light weight, and is of great practical value.
Scandium mainly plays the role of modification and grain refinement in the alloy, which

makes the Al3Sc type of new phase and presents the characteristics of excellent

performance. Al-Sc alloy has formed a series of alloy series, such as Russia has reached 17

kinds of Al-Sc series, my country also has several alloys (such as Al-Mg-Sc-Zr and Al-Zn-

Mg-Sc alloy). 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 industrialized production, and it is used for light structural parts to

develop rapidly. my country is also accelerating its development and application,

especially in aerospace and aviation.

 
Application of new electric light source materials

 
After converting pure Sc2O3 into ScI3, a new third-generation electric light source

material is made with NaI, and processed into a scandium-sodium halogen lamp for

lighting (each lamp uses about 0.1mg ~ 10mg of Sc2O3 ≥ 99% material. This Under the

action of high-voltage electricity, the scandium spectral line is blue and the sodium

spectral line is yellow. The two colors cooperate with each other to produce light close to

sunlight, so that the light has high luminosity, good light color, energy saving and

longevity. It has the advantages of long and strong fog breaking power.

 
Applications in Laser Materials

 
Gadolinium gallium scandium garnet (GGSG) can be made by adding pure Sc2O3 ≥

99.9% to gadolinium gallium garnet (GGG), which is composed of Gd3Sc2Ga3O12 type.

The emission power of the third-generation laser made of it is 3.0 times higher than that

of the laser of the same volume, and it has reached a high-power and miniaturized laser

device, which improves the output power of laser oscillation and improves the

performance of the laser. When preparing single crystal, each charge is 3kg-5kg, and the

raw material added with Sc2O3 ≥ 99.9% 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 also

gradually promoted to the civilian industry. From the perspective of development, it has

great potential for military and civilian use in the future.

 
applications in electronic materials

 
Pure Sc2O3 can be used as the oxidizing cathode activator of the cathode electron gun of

color TV picture tube with good effect. Spray a layer of Ba, Sr, Ca oxide layer with a

thickness of 1 mm on the upper end of the cathode of the color tube, and then disperse a

layer of Sc2O3 with a thickness of 0.1 mm on it. In the oxide layer cathode, Mg, Sr and Ba

react to promote Ba reduction, the released electrons are more active, and high current

electrons are emitted to make the phosphor emit light. Compared with the cathode

without Sc2O3 coating, the current density can be increased by 4 times, making the 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 was 0.1 mg. At present, this cathode has

been used in some countries in the world, such as Japan, which can improve the market

competitiveness and promote the sales of TV sets.
