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: 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'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;

Q: What is the difference between a multicomponent alloy and a rare earth alloy?: Aluminum is an alloy of aluminum and copper, magnesium and manganese. This alloy is suitable for pressing and forming. The strength and hardness of the alloy are much larger than those of general aluminum.

Q: What's the use of rare earth?: At present, rare earth has been widely used in metallurgy, petroleum, chemical, textile, medicine, agriculture and other dozens of industries. For example, rare earth steel can significantly improve the wear resistance, corrosion resistance and toughness of steel; rare earth aluminum wire rod can improve the strength and conductivity at the same time reduce the fineness of aluminum; rare earth pesticide in fruit, can kill the pests, but also can improve the fruiting rate; rare earth compound fertilizer can improve soil structure, and can improve the output of agricultural products; rare earth catalyst for China's oil refining industry, cost less than 100 million yuan, but the gasoline and light oil output efficiency many times.

Q: Rare earth in the end what to do ah?: Military: 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.Metallurgical Industry: rare earth metal silicide or fluoride, added to steel, to refining, desulfurization, and low melting point of harmful impurities, and can improve the processing performance of steel; 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 and other 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.

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: The position of rare earth elements in the periodic table of the element is very special. The 17 elements are in the first element of the transition element series in group III, B, scandium, yttrium and lanthanum, respectively, for fourth, fifth, sixth and long cycles. The 14 elements of nature and LA are very similar, chemists can only put them in a lattice, no wonder some people regard them as "isotope" approach, but because of their different atomic numbers, also cannot be counted as true isotope. That is to say, their properties are very similar, but not exactly the same, which resulted in this group of elements is difficult to separate, but also shows that as long as the use of the very small difference, and separation is possible; on the other hand, their electronic structure has an inner electronic layer is not completely filled, namely 4f layer. Because of the difference in the number of electrons in the 4f layer, each element of the group has a very specific personality, especially the optical and magnetic properties, like a keyboard with a full range and a wide range of pianos.

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!
