Technical Field

[0002] Rare earth metals are the general names of 17 elements including scandium, yttrium, and lanthanide series in Group IIIB of the periodic table, commonly represented by R or RE. Since they often coexist with other elements in a dispersed state, their extraction and separation become extremely difficult, so they are named "rare earths". Rare earth metals have a wide range of applications in petrochemical industry, chemical synthesis, environmental protection, etc. The most prominent one is the catalytic effect. Rare earth metals have special electronic structures and energy level distributions, which can stimulate the interaction between various substances in the reaction, promote the progress of the reaction, and improve the reaction rate and selectivity. In addition, rare earth metals also have good stability and corrosion resistance, and can be used in high temperature, high pressure, strong acid, and strong alkali environments. Rare earth metal smelting is a complex and delicate process, involving multiple steps and technologies. Rare earth metals are widely used in multiple fields due to their unique physical and chemical properties and have become an important raw material indispensable to modern industry. With the continuous progress of technology and the in-depth understanding of the concept of sustainable development globally, the application prospects of rare earth metals will be even broader.
