What are rare earths?

Rare Earths is a ‘Rare Earth’. In fact, this is just a misunderstanding left over from the 18th century. Several rare-earth elements were discovered after 1787, but few minerals were found. Due to the limitations of science and technology at that time, people could only make some impure, soil-like oxides, so people gave this group of elements such a unique and interesting name.

What elements are contained in rare earths?

Rare EarthsRare Earth is chemical lanthanide elements in the periodic table – lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium (Nd), promethium (Pm), samarium (Sm), europium (Eu), gadolinium (Gd), terbium (Tb), dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), ytterbium (Yb), lutetium (Lu), and 15 with lanthanide elements is closely related to the two elements – scandium (Sc) and yttrium (Y), a total of 17 elements, known as Rare Earth elements (Rare Earth). Rare earth (RE or R) for short.

Why do we need rare earths?

Rare earths are essential to many advanced industrial raw materials. Rare earth is a new functional material with electrical, magnetic, optical, biological and many other characteristics . It is the important foundation materials for high-tech fields and national defense construction such as information technology, biotechnology, energy technology. Also it has reformed some traditional industries in agriculture, chemical industry, building materials. Rare earth is widely used, there are many kinds of functional materials that can be used in rare earth, and a large-scale high-tech industrial group is forming, which has a very broad market prospect and extremely important strategic significance.
