Q:What's the stability of rare earth calcium zinc stabilizer? What are the advantages?: Non-toxic, environmentally friendly, non radioactive. Can improve the production environment, labor conditions, reduce environmental pollution, and its products can be detected by the SGS international testing institutions and ROHS standards.

Q:Use of rare earth? Which industries depend on him?: The rare earth industry "gold", because of its excellent photoelectric magnetic and other physical properties, and other materials composed of new materials, the performance of different varieties, the most obvious function is to greatly improve the quality and performance of other products. For example, the tactical performance of steels, aluminum alloys, magnesium alloys and titanium alloys for tanks, aircraft and missiles has been greatly improved. What's more, rare earth is also a high-tech lubricant for electronics, lasers, nuclear industry, superconductivity, and so on. Once used in military affairs, rare earth technology will inevitably bring about a leap in military technology. In a sense, the US military's partial wars in the cold war, the backward sex control, and the unbridled and open killing of the enemy are due to the superman in the field of rare earth science and technology.

Q:Pink and what is the difference between rare earth polishing powder: Cerium based rare earth polishing powder is one of the most important rare earth products.Because of its strong ability of cutting, polishing and polishing time is short, high precision, clean operation environment and other advantages, so other than polishing powder (such as pink Fe2O3) the good use effect, known as "the king of polishing powder".

Q:Method for processing rare earth ore: Warehouse workshop of water: commonly known as the boiler room, this should be a soft water, which is distilled water, in particular in production of this water, because there is no mixed material here.

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: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:What's the use of rare earth?: Rare earth materials are used as the key to many major weapons systems, it is also a lot of sophisticated industrial essential raw materials, rare earth elements have electric, magnetic, optical, biological and other properties, is an important basic material information technology, biological technology, energy technology and other high technology fields and national defense construction, at the same time on the transformation of some traditional industries, such as agriculture, chemical industry, building materials and other plays an important role

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!

Q:What's the use of rare earth? Why Japan wants to buy Chinese rare earth?: Rare earth is also the electronic, laser, nuclear, superconducting and many other high-tech lubricants. Once used in military affairs, rare earth technology will inevitably bring about a leap in military technology. In a sense, the US military's partial wars in the cold war, the backward sex control, and the unbridled and open killing of the enemy are due to the superman in the field of rare earth science and technology. In the metallurgical industry, rare earth metals or fluorides and silicides can be added to steel to play the role of refining, desulfurization, neutralization and low melting point harmful impurities, and can improve the processing performance of steel;
