As far as 5G mobile phones are currently hot topics, their measurement and control devices, vibration motors, speakers, screens, lenses and other components are closely related to rare earths. This also shows that the arrival of the mobile 5G era will contribute to the high quality of the rare earth industry. development of.
In the Baiyun Obo mining area, the world's largest rare earth mine, it is almost impossible to recruit new drivers due to poor working conditions and high personnel safety risks. However, with the opening of the 5G curtain, China Mobile Inner Mongolia, in conjunction with Baotou Steel Group, Huawei, and Tage Zhixing, Baidu and other partners, implemented the "smart mine" development action plan to create a "5G + smart mining area" project in the Baiyun Obo mining area. Realize unmanned driving of mining trucks and unmanned operation of mining equipment, as well as automated management of mine production, operation and dispatch. This also shows that the development of 5G will make the rare earth industry structure more perfect.
So, how are rare earth materials used in 5G mobile phones?
1. Rare earths in mobile phone screens
Because these rare earth ions, such as lanthanum, terbium, praseodymium, europium, etc., have rich emission spectra, they are used on mobile phone screens. In other words, rare earth elements are key materials for color display on mobile phone screens.
2. Rare earths in mobile phone lenses
Rare earth lanthanum oxide (La2O3) is a new high-quality optical glass material with high refractive index and low dispersion. It is often used to make read-write lenses and imaging lenses for optoelectronic products, which can effectively expand the field of view of the lens and improve The imaging quality of the instrument makes the lens smaller and lighter.
3. Application of rare earth permanent magnets in mobile phones
The neodymium iron boron permanent magnet, known as the "magnet king", is an indispensable high-end component of smart phones, mainly used in its electro-acoustic parts, imaging systems, and parts of measurement and control devices.
4. Rare earths in mobile phone batteries
Compared with similar batteries, the advantages of lithium batteries containing rare earth materials are as follows: due to the addition of rare earth elements, the charging stability of the battery is significantly improved, and the structural stability of the material is also ensured, which effectively improves and improves the cycle performance of the battery . In addition, rare earth elements expand the three-dimensional channel for lithium ion migration, effectively improving the reversibility of the electrochemical cycle of the material, and thereby extending the battery life.
In the future, the arrival of the 5G era will bring the Internet to a new stage and realize more possibilities. With the rapid development of mobile 5G, the development of the rare earth industry will surely be further improved.
