These 17 elements are collectively called rare earth elements. They have certain similarities in chemical properties and usually coexist in mineral form in nature. The names of these elements come from their historical discovery process. The term "rare earth" is derived from the fact that the minerals used to extract these elements were relatively rare at the time, and the oxides obtained were difficult to melt, dissolve in water, and separate, and their appearance resembled "soil".

Rare earth elements have a wide range of applications in many fields, including metallurgy, petrochemicals, glass and ceramics, agriculture, electronic information, and new energy. They play an important role in the development of modern industry and technology, and are known as "industrial vitamins" or "the mother of new materials."
