Rare Earth
RE has been widely used in various aspects of the traditional areas of metallurgy, machinery, petroleum, chemicals, glass, ceramics, textiles, leather, farming, breeding.

RE applications:
• fluorescent material

• rare earth metal hydride battery materials
• source material
• Permanent Magnetic Materials
• hydrogen storage material
• catalytic material
• Precision Ceramics
• laser materials
• superconducting material
• magnetostrictive material
• magnetic refrigeration material
• magneto-optical storage materials
• fiber materials

Rare earth elements include Sc, Y and La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, a total of 17 elements.

Rare earth elements are divided into "light rare earth elements" and "heavy rare earth elements":
"Light rare earth elements" refers to the atomic number smaller La, Ce, Pr, Nd, Pm, Sm, Eu, Gd
"Heavy rare earth element" atomic number larger Tb, Dy, Ho, Er, Tm, Yb, Lu, Sc, Y
