What are the applications of rare earths in daily life?

Metallurgy - machinery manufacturing One of the three traditional areas

Steel adding trace amounts of rare earths can improve the strength, toughness, wear resistance and corrosion resistance of steel. Aluminum, magnesium, copper and other non-ferrous metal alloys to add rare earths can refine the grain significantly improve the overall performance. Rare earths used in aluminum cables can improve material strength, electrical conductivity and corrosion resistance.

Petrochemical

Rare earths can be used as catalysts for many inorganic and organic chemical reactions. Used in catalytic cracking refining crude oil, can significantly increase the yield of light oil. Direct distillation of petroleum only 15-20% of the gasoline, and rare earth catalytic cracking gasoline can be

up to 80% of the crude oil. Rare earth catalysis is also used in motor vehicle exhaust purification, synthetic rubber, paint drying, plastic stabilizers and rare earth polymer materials and many other fields.

Glass ceramics, one of the important traditional applications of rare earths rare earths in the glass industry is used as optical glass additives, clarifiers, decolorants, coloring agents and polishing powder.

Defense and cutting-edge technology, rare earth permanent magnet devices are used in rocket rare earth permanent magnet devices are used in the launch of the "Shenzhou 5" manned spacecraft Long March 2 f-type rockets; and the "Long March 3B" bundled carrier rockets, the success of the "Asia-Pacific 6", the "Long March 3B", the success of the "Long March 3B" bundled carrier rockets, the success of the "Long March 3B". "Asia-Pacific-6"

communications satellite into space.

Rare-earth nickel-metal hydride (NiMH) power supplies are the preferred secondary power source for the development of the most practical applications of electric vehicles.

Compared with the traditional chemical power supply (such as lead-acid, nickel-cadmium, etc.), nickel-metal hydride power batteries have non-polluting, high-energy, high-power, fast charging and discharging, durability, and many other excellent characteristics, with a broad application and market prospects.

The king of permanent magnets - NdFeB, neodymium and praseodymium alloys are mainly used in the manufacture of NdFeB permanent magnetic materials, used in permanent magnetic motors, generators, nuclear magnetic *** vibration imager, magnetic separator, audio speakers, magnetic drive, magnetic lifting, instruments and meters, liquid magnetization, magnetic therapy equipment and so on.
