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?: In the military aspects of 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.

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.

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?: 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 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: More than 10 kinds of metal oxides, such as aluminum, zinc, chromium, manganese, titanium, zirconium, silicon, iron and rare earth, have been used in industry.In the polishing powder polishing effect of cerium based polishing powder is best, it has been replaced by other polishing powder (such as SiO2, ZrO2 and Fe2O3) applications, so there will be a cerium based rare earth polishing powder, known as the "king of polishing powder".

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!
