Q: What's the stability of rare earth calcium zinc stabilizer? What are the advantages?: The dispersion and anti decomposition properties of rare earth calcium zinc stabilizer are better than that of lead salt stabilizer, and the color, brightness and firmness of the product are improved. Besides, the defects that lead salts are easy to generate sulfuration pollution are avoided.

Q: Method for processing rare earth ore: Is to put the outside of the feed fluid (carbonic acid rare earth mixture) into the acid dissolved inside, and now one side of the equipment is operating, the operation is relatively simple, it was difficult to manually deploy before.

Q: What's the use of rare earth? Why Japan wants to buy Chinese rare earth?: Rare earth ferrosilicon alloy, rare earth silicon magnesium alloy as spheroidizing agent in the production of rare earth nodular cast iron, ductile cast iron, because this is particularly suitable for the production of the special requirements of the complex ductile iron, are widely used in automobile, tractor, diesel engine and other mechanical manufacturing; rare earth metals added to magnesium, aluminum, copper, zinc, nickel, etc. non-ferrous alloys, physical and chemical properties of the alloys can be improved, and improve the mechanical properties of alloy at room temperature and high temperature. Made of rare earth molecular sieve catalyst in petroleum chemical industry, has the advantages of high activity, good selectivity and strong resistance to heavy metal poisoning, which replaces the aluminum silicate catalyst used in petroleum catalytic cracking process; in ammonia production process, with a small amount of rare earth nitrate as catalyst, its treatment capacity than Ni Al catalyst 1.5 times; in cis-1,4-polybutadiene rubber and isoprene rubber in the process of using naphthenic acid rare earth aluminum products three kinds of catalyst, the obtained performance is excellent, with less equipment fubberized, stable operation, postprocessing the advantages of short process; composite rare earth oxides can also be used as an internal combustion engine exhaust purification catalysts, cerium naphthenate also can be used as paint drying agent.

Q: What is the difference between a multicomponent alloy and a rare earth alloy?: Multicomponent alloy (multielementalloy) means an alloy made up of more than two components. Such as Fe-Cr-Al alloy, Ni-Cr-Mo alloy, Fe-Cr-Ni-Mo alloy and so on.Such as Fe-Cr-Al alloy, Ni-Cr-Mo alloy, Fe-Cr-Ni-Mo alloy and so on.Most of the practical metals belong to multicomponent alloys.All industrial steels are iron base alloy.Rare earth iron alloy, is a combination of rare earth elements with iron, rare earth alloy for different uses, the content of rare earth elements are different, which are iron, gadolinium iron dysprosium neodymium iron boron additive of rare earth elements in high purity, China is the world's largest supplier of rare earths, representing the world's supply of rare earths 97% at present, rare earth as an irreplaceable resource is widely used in many high-tech industries, including wind turbines, hybrid vehicles, missiles and mobile phone etc..

Q: What's the use of rare earth?: Is the chemistry of rare earth elements in the periodic table lanthanides (La) cerium, lanthanum, praseodymium (Ce) (Pr), neodymium (Nd), promethium (Pm), samarium (Sm) and europium (Eu), gadolinium (Gd), terbium (Tb), dysprosium, holmium (Ho (Dy)), ER (Er), (Tm), thulium ytterbium lutetium (Yb), (Lu), and 15 with lanthanide two elements closely related to scandium (Sc) and yttrium (Y) a total of 17 kinds of elements known as rare earth elements (Rare, Earth). Rare earths (RE or R). Rare earth (rare, earth) has "industrial vitamins" laudatory name. Now it has become a very important strategic resource. Rare earth oxide refers to the elements in the periodic table of atomic number from 57 to 71 of the 15 Lanthanide Oxides, as well as with the lanthanide elements similar to the chemical properties of scandium (Sc) and yttrium (Y) oxides of 17 elements. Rare earth elements have been widely used in the fields of petroleum, chemical, metallurgy, textile, ceramics, glass, permanent magnet materials, with the continuous progress of science and technology breakthrough and application technology, rare earth oxide value will become more and more large.

Q: Rare earth in the end what to do ah?: Is the chemistry of rare earth elements in the periodic table lanthanides (La) cerium, lanthanum, praseodymium (Ce) (Pr), neodymium (Nd), promethium (Pm), samarium (Sm) and europium (Eu), gadolinium (Gd), terbium (Tb), dysprosium, holmium (Ho (Dy)), ER (Er), (Tm), thulium ytterbium lutetium (Yb), (Lu), and 15 with lanthanide two elements closely related to scandium (Sc) and yttrium (Y) a total of 17 kinds of elements known as rare earth elements (Rare, Earth).

Q: Use of rare earth? Which industries depend on him?: The catalyst with molecular sieve made of rare earth, has the advantages of high activity, good selectivity and strong resistance to heavy metal poisoning, which replaces the aluminum silicate catalyst used in petroleum catalytic cracking process; in ammonia production process, with a small amount of rare earth nitrate as catalyst, the gas volume is 1.5 times bigger than in Ni Al catalyst; synthesis of isoprene rubber and butadiene rubber in the process of using naphthenic acid rare earth aluminum products three kinds of catalyst, the obtained performance is excellent, with less equipment fubberized, stable operation, postprocessing the advantages of short process; composite rare earth oxides can also be used as an internal combustion engine exhaust purification catalysts, cerium naphthenate is also used as a paint drier etc..

Q: Pink and what is the difference between rare earth polishing powder: Because of the chemical and physical properties better with cerium based polishing powder, so it has been widely used in industrial products such as polishing, polishing in various optical glass devices, television picture tube, optical glasses, tube, plate glass, semiconductor wafer and precision metal products etc..

Q: Why should China export rare earths at a low price?: Indium, an important raw material for LCD panels. China banned the export of rare earth, so that the Taiwan region, Japan and South Korea and other countries of the LCD manufacturers tremble with fear, the international market, the LCD facial prices rose!
