î´ î´ 1843 Sweden's Mo Sangde (Karl G.Mosander) through the study of the earth yttrium, terbium found elements (Terbium). Most of the applications of 铽 involve high-tech fields, are technology-intensive, knowledge-intensive and cutting-edge projects, and are projects with significant economic benefits, which have attractive development prospects.

The main application areas: (1) an activator for the phosphor in the green three-color phosphor powder, such as terbium activated phosphate matrix, terbium-activated silicate matrix, terbium-activated cerium magnesium aluminate matrix , emits green light in the excited state. (2) Magneto-optical storage materials. In recent years, lanthanide magneto-optical materials have reached the scale of mass production. Magneto-optical discs developed with Tb-Fe amorphous films are used as computer storage components, and the storage capacity is improved by 10 to 15 times. (3) Magneto-optical glass, ytterbium-containing Faraday rotatory glass is a key material for the manufacture of rotators, isolators and circulators that are widely used in laser technology. In particular Terfenol alloy (TerFenol) is developed,
It is a new use for cockroaches. Terfenol is a new type of material discovered in the 1970s. Half of the alloy is bismuth and antimony. Sometimes it is added with antimony and the rest is iron. The alloy is tested by the American Armas Edwards. The chamber was first developed, and when Terfenol was placed in a magnetic field, the change in size was greater than that of a typical magnetic material. This change allowed some precise mechanical motion to be achieved. NdFe began to be used primarily in sonar and is now used in a wide variety of applications, from fuel injection systems, liquid valve control, micro-positioning to mechanical actuators, mechanisms and aircraft wing telescope adjustment wing regulators.
