The main uses of scandium
The main uses of scandium
The use of scandium (as the main working substance, not for doping) is concentrated in a very bright direction, and it is not an exaggeration to call it the Son of Light.
1. Scandium sodium lamp
The first magic weapon of scandium is called scandium sodium lamp, which can be used to bring light to thousands of households. This is a metal halide electric light source: sodium iodide and scandium iodide are charged into the bulb, and scandium and sodium foil are added. During high-voltage discharge, scandium ions and sodium ions emit their characteristic emission wavelengths of light, respectively. The spectral lines of sodium are two famous yellow lines, 589.0nm and 589.6nm, while the spectral lines are a series of near ultraviolet and blue light emissions from 361.3-424.7nm. As they complement each other, the overall color produced is white light. It is precisely because scandium sodium lamps have the characteristics of high luminous efficiency, good light color, power saving, long service life, and strong fog breaking ability that they can be widely used for television cameras, squares, sports venues, and road lighting, and are known as the third generation light sources. In China, this type of lamp is gradually being promoted as a new technology, while in some developed countries, this type of lamp was widely used as early as the early 1980s.
2. Solar photovoltaic cells
The second magic weapon of scandium is solar photovoltaic cells, which can collect the light scattered on the ground and turn it into electricity to drive human society. In metal insulator semiconductor silicon solar cells and solar cells, it is the best barrier metal.
3. γ Radiation source
The third magic weapon of scandium is called γ A ray source, this magic weapon can shine brightly on its own, but this kind of light cannot be received by the naked eye, it is a high-energy photon flow. We usually extract 45 Sc from minerals, which is the only natural isotope of scandium. Each 45 Sc nucleus contains 21 protons and 24 neutrons. 46Sc, an artificial radioactive isotope, can be used as γ Radiation sources or tracer atoms can also be used for radiotherapy of malignant tumors. There are also applications such as scandium garnet lasers, fluorinated glass infrared optical fiber, and cathode ray tubes coated with scandium on televisions. It seems that scandium was born with light.
4. Magic seasoning
The above mentioned some applications of scandium, but due to its high price and cost considerations, a large amount of scandium and scandium compounds are rarely used in industrial products, using a thin layer of foil like in a light bulb. In more fields, Hetong compounds are used as magical seasonings, like salt, sugar, or monosodium glutamate in the hands of chefs. With just a little bit, they can make the finishing touch.
5. Impact on people
It is currently uncertain whether scandium is an essential element for humans. Scandium is present in trace amounts in the human body. Suspected of carcinogenicity. Scandium is prone to form complexes with 8-light groups, which can be used for the analysis of scandium. Neutron radiometric analysis can be used to determine the quantification below ng/g.
