Rare earth elements are found in relatively rare minerals. "Soil" originally refers to substances that are insoluble in water, so it is called rare earth. English Rare Earth Element (short for RE or R). 15 is a rare earth element from the family of lanthanides, together with closely associated with the lanthanide and yttrium scandium total of 17 elements. They are: 镧, 铈 , 镨 , é’• , é’·, é’ , é“• , é’† , 铽 , é• , é’¬ , é“’ , é“¥ , 镱 , é•¥ , é’ª, é’‡. If you want to call a certain member of this family in Chinese, you don't have to worry about the " gold " that is attached to you. You can directly call the "name" on the side, and you will not leave the 10th. Rare earth is a magical family. Natural rare earth elements are often accompanied by people, and people must find ways to separate them. In the early days of cognition of rare earths, humans often get some kind of rare earth elements, but they don't know that there are other "naughty" elements hidden in them, or they can't separate partners who don't want to break up. For example, "镧" is found in "铈", and its name "La" is the abbreviation of the Greek word "hidden". "镨钕" means "twin" in Greek, and "镨钕" is found in the middle of "镧", and after 40 years, they are separated into two elements, so one is called "镨", The other one is named "é’•". Also, "é’" is found in "镨钕", and "é’†" is found in "é’". Due to the special atomic structure, the members of the rare earth family are very lively and unique, and the magic is boundless. Combined with other elements, they can form a new variety of materials with ever-changing functions and different uses, and their performance is doubled. It is called the contemporary "industrial MSG." Such as: Application of supersonic aircraft contained in the rare earth alloy ÐЦР1 and ЖП207, less long-term work at 400 ℃, which today is one of the best high temperature performance of the alloy, its rupture strength than ordinary aluminum alloys can be increased 1-2 times ; After the rare earth is added to the steel, the transverse impact toughness of the thin material is increased by more than 50%, the corrosion resistance is improved by 60%, and the effect of adding rare earth is about 300 grams per ton of steel, the effect is very significant, and it can be said that four or two pounds; Rare earth is added to acid textile dyes to improve dye uptake, adjust dye and fiber affinity, improve dyeing fastness, improve fiber color, appearance quality and hand softness, save dyes, reduce environmental pollution and reduce labor intensity. Wait; Rare earth elements can increase plant chlorophyll content, enhance photosynthesis, promote root development and nutrient uptake. It can also promote seed germination and promote seedling growth, and also has the ability to enhance crop disease resistance, cold resistance and drought resistance; The use of rare earth lanthanum as a heat source provides auxiliary energy for vacuum detection and satellites. The battery can be used as a power source for missile guidance instruments and watches. This battery is small and can be used continuously for several years. In today's world, whether it is aerospace, aviation, military and other high-tech fields, or people's daily necessities, regardless of industry, agriculture, animal husbandry, or chemistry, biology, medicine, the application and role of rare earths is almost ubiquitous. omnipotent.
