  Rare is the chemical periodic table of lanthanides - 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 the lanthanide elements 15 are closely related to two elements - scandium (Sc) and yttrium (Y) of 17 kinds of elements, called rare earth elements (Rare Earth). Referred earth (RE or R). My company's products are mainly lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium (Nd), samarium (Sm), europium (Eu), gadolinium (Gd).

■ lanthanum(La)
 

  "Lanthanum" element is named 1839, a man named "Mo Sangde," the Swede found ceria containing other elements, he borrowed the Greek word "hide" the word put this element named "La" .
Mainly used in piezoelectric materials, electric materials, thermoelectric materials, magnetoresistive materials, luminescent materials (blue powder), hydrogen storage materials, optical glass, laser materials, various alloy materials. She also applied to the preparation of a catalyst for many organic chemical products, light is converted agricultural film also uses lanthanum, in foreign countries, scientists lanthanum effect on crops confer "super calcium" reputation.

 
     

■ Cerium(Ce)
 

  "Ce" element by German Claudia Pross, Swedes , the Greek Health Siegel in 1803 discovered and named to commemorate the 1801 discovery of asteroids - Ceres.
Mainly used in glass additives, has been widely used in the automotive glass. Since 1997, the Japanese auto glass full join ceria, 1996 cerium oxide for automotive glass at least 2,000 tons, the United States about 1000 tons. Cerium broad range of applications, almost all application areas contain rare earth cerium. Such as polishing powder, hydrogen storage materials, thermoelectric materials, cerium tungsten electrodes, ceramic capacitors, piezoelectric ceramics, silicon carbide abrasive cerium, fuel cell materials, gasoline catalysts, some permanent magnet materials, a variety of alloy steel and non-ferrous metals.

 
     

■ Praseodymium(Pr)
 

     Aound 160 years ago, the Swedes Mo Sangde from lanthanum discovered a new element, but it is not a single element, Mo Sangde found that the elements lanthanum is very similar in nature, they put their named "praseodymium neodymium" . "Praseodymium neodymium" Greek for "twins" means. Then, after about 40 years, which is the invention Qidengshazhao of 1885, the Austrians Wells Bach successfully from "praseodymium neodymium" isolated two elements, one named "neodymium" and the other is named "Pr." This "twins" are separated, and praseodymium elements also have their own vast world to display their talent. Pr is a larger amount of rare earth elements, which for glass, ceramics, petroleum cracking, and magnetic materials in the polishing abrasive. 

 
 
 
     

■ Neodymium(Nd)
 

     Wth the birth of the element praseodymium, neodymium elements have emerged, neodymium rare earth elements active in the field of the arrival in the field of rare earth plays an important role, and about the rare earth market.
       Ndymium is the largest user of NdFeB permanent magnet materials. The advent of NdFeB magnet, rare earth high-tech sector has injected new vigor and vitality, is called contemporary "magnet of the King", with its excellent performance is widely used in electronics, machinery and other industries. Neodymium is also used in non-ferrous materials. The magnesium or aluminum alloy with 1.5% to 2.5% neodymium, the alloy can be improved high temperature performance, corrosion resistance, air tightness and widely used as aerospace materials. Furthermore, neodymium-doped yttrium aluminum garnet laser beam generating short, is widely used in industry below 10mm thin material thickness for welding and cutting. On health care, neodymium-doped yttrium aluminum garnet laser instead of a scalpel is used to disinfect a wound or surgical removal. Neodymium is also used for coloring glass and ceramics and rubber additives.

 
     

■  Samarium(Sm)
 

  1879, Beuys package Dresser yttrium niobium ore obtained from "praseodymium neodymium" rare earth elements in the discovery of new, and according to the name of this mineral is named samarium.  
     Pale yellow samarium, samarium cobalt permanent magnets do a raw material, samarium cobalt magnets are the first industrial applications obtained rare earth magnet, samarium oxide catalysts for ceramic capacitors and aspects. Samarium also has a nuclear nature, can be used as nuclear reactor structural materials, shielding materials and control materials to make nuclear fission produces huge amounts of energy to ensure the safe use.

 
     

■  Europium(Eu)
 

 In 1901, Eugene-Antole Demarcay From the "SM" in the discovery of new elements, named Eu (Europium). This is probably based on the European (Europe) word naming. Europium oxide phosphor mostly used, improve the luminous efficiency and contrast, etc. play a larger role, it is being widely used. In recent years, europium oxide is also used in the new X-ray medical diagnosis system stimulated emission phosphors. Europium oxide can also be used to manufacture colored lenses and optical filters for magnetic bubble storage device, the control of materials at the atomic reactor, shielding and structural materials can also be a go.

 
     

■  Gadolinium(Gd) 
 

  1880, Switzerland G.de Marignac The "SM" is separated into two elements, one of which is confirmed by the Suo Lite samarium, another element to get Beuys package Dresser research confirms, in 1886, to commemorate Marignac discoverer of rare earth elements yttrium pioneer Dutch chemist Gadolin (Gado Linium), will be named the new element gadolinium. Gadolinium in modern technologies will play an important role in innovation, and its water-soluble paramagnetic complexes in medical MRI can improve the body (NMR) imaging signal. Nuclear chain reaction used to control the levels of inhibitors in order to ensure the safety of nuclear reactions. In addition, gadolinium and lanthanum oxide used to help change the glass transition region and improving the thermal stability of the glass. Gadolinium oxide can be used for manufacturing a capacitor, x-ray intensifying screens.
