1. Metallurgical industry

Rare earths are widely used in the metallurgical industry, accounting for about 1/3 of the total use of rare earths. Adding rare earths to molten steel can play the role of desulfurization and deoxidation, improve the normal and low-temperature toughness and fracture resistance of steel, as well as the heating workability and the firmness of welded parts.

Rare earths serve as graphite nodularizing agents in cast iron, which can improve the quality of castings and improve the mechanical properties of castings.

For nonferrous metals such as aluminum, magnesium, and copper, the addition of rare earths can significantly improve their physical and mechanical properties.

2. Petrochemical industry

Rare earth catalysts play an important role in the petroleum cracking industry, increasing the productivity of gasoline.

Rare earths are also used as catalysts in the production of synthetic ammonia, rubber, etc. They have the advantages of high activity, good selectivity, and oxidation, which help improve industrial production efficiency and quality.

3. Glass ceramics

In the glass industry, rare earths are used for glass coloring, glass decolorization and the manufacture of radiation-proof glass, optical glass, etc.

Rare earth oxides are also widely used in the ceramic industry as ceramic pigments and important materials for manufacturing high-temperature-resistant transparent ceramics, high-temperature-resistant crucibles, etc.

4. Agriculture

As plant growth and physiological regulators, rare earths have three major characteristics: increasing yield, improving quality and stress resistance of crops. The rational use of rare earths can enhance the ability of crops to resist drought, floods and lodging.

5. Electronic information

Rare earths are the main raw materials for manufacturing modern super permanent magnet materials, such as neodymium, samarium, praseodymium, dysprosium, etc., and are known as the "King of Permanent Magnets". These materials are used in permanent magnet motors, generators, magnetic resonance imaging machines, magnetic separators, audio speakers, magnetic transmission, magnetic lifting, instrumentation, liquid magnetization, magnetic therapy equipment, medical equipment, acoustic and electrical equipment, maglev trains and military It is widely used in industry and other fields.

Rare earths are also the luminescent material of fluorescent lamps, which can save 75% to 80% of electricity compared to incandescent lamps.

6. New energy

Rare earth nickel-hydrogen power batteries have many excellent characteristics such as non-pollution, high specific energy, high power, rapid charge and discharge, and resistance to abuse, and have broad application and market prospects.

Rare earth hydrogen storage materials can absorb and release hydrogen at lower temperatures. They are functional materials with great development potential and strategic materials in the field of green energy. They are mainly used in high-performance rechargeable nickel-metal hydride batteries.

7. Other areas

Rare earths also have important applications in the manufacture of precision ceramics and artificial gemstones. For example, artificial gemstones processed with yttrium oxide and zirconium oxide have many characteristics that natural gemstones do not have.

Cerium oxide in rare earths is an extremely effective polishing compound and has been widely used in the polishing of industrial products, such as various optical lens glass, spectacle lenses, flat glass, craft glass, mobile phone screen glass, semiconductor wafers and metal precision products Waiting for polishing.

Rare earths are also used in the manufacture of superconducting materials, laser materials, catalysts and other fields, promoting the development of materials science and technology.
