- 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: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?
- 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, nodular cast iron because this is particularly suitable for the production of special the complex requirements of nodular iron castings, 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 alloy at room temperature and high temperature mechanical properties.
- Q:What's the use of rare earth? Why Japan wants to buy Chinese rare earth?
- In the aspect of glass ceramics with rare earth oxide or rare earth concentrate after processing, can be used as a polishing powder is widely used in polishing of optical glass, glass sheet, tube, tube, plate glass, plastic and metal tableware; in the glass melting process, using two cerium oxide has very strong oxidation of iron. Reduce the content of iron in glass, in order to achieve the purpose of removing the green glass; rare earth oxides can be made of optical glass and special glass for different purposes, including through infrared, ultraviolet absorbing glass, acid resistant and heat-resistant glass, - X- - ray glass; rare earth in ceramic glaze and glaze. Fragmentation can reduce the glaze, and can make the products show different color and luster, is widely used in ceramic industry. In terms of new material of rare earth cobalt and neodymium iron boron permanent magnetic material, with high remanence, high coercivity and high energy product, is widely used in electronic and aerospace industries; pure rare earth oxides and iron oxide into combinations of garnet single crystal and polycrystal, can be used in microwave and electronic industry;
- Q:Method for processing rare earth ore
- Heavy rare earth extraction workshop, extraction workshop, light rare earth yttrium chloride workshop is mainly for separation (based on several different acid solubility), the front of the separation of rare earth carbonate into nitric acid, chloride, carbonate from single element. These can also be sold.
- Q:Why should China export rare earths at a low price?
- Rare earth has always been a national strategic resource, and is regarded as the key to the future world.While China's Baiyunebo rare earth ore accounts for 90% of the world's recoverable resources, and 70% of the world's rare earth consumption is exported to China, so Chinese geologists call rare earth "the only blessing God has for the suffering Chinese."". But because of uncontrolled exploitation, wanton export traitorous comprador, coupled with Japan strategic alliance to keep the prices down, in the rare earth resources in the international market prices even offset back mining cost. This kind of situation, people can not help but burst into tears!
- 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:What is the difference between a multicomponent alloy and a rare earth alloy?
- The content of aluminum and aluminum is very high, and it is relatively pure aluminum. It is soft and can be rolled into various shapes. The daily use of aluminum, aluminum boxes, aluminum sheet, aluminum, aluminum, aluminum is cooked to do. An alloy consisting of two or more than two metals and metals or nonmetals synthesized by a certain method with metallic properties. Usually obtained by fusion of homogeneous liquid and solidification. According to the number of constituent elements, can be divided into two yuan alloy, three yuan alloy and multi-element alloy.
