Uses of the rare earth element praseodymium (Pr).
Praseodymium (Pr) About 160 years ago, the Swede Mosander discovered a new element from lanthanum, but it was not a single element, Mosander found that the properties of this element were very similar to lanthanum, so he named it "praseodymium neodymium". "Praseodymium" means "twins" in Greek. About 40 years later, in 1885, the year of the invention of the gas lamp gauze, the Austrian Wellsbach succeeded in separating two elements from "praseodymium-neodymium", one named "neodymium" and the other "praseodymium". This "twin" is separated, and the praseodymium element also has the breadth of its own talents
Uses of the rare earth element neodymium (Nd).
Neodymium (Nd) With the birth of praseodymium, neodymium also came into being, and the arrival of neodymium has enlivened the rare earth field, playing an important role in the rare earth field and influencing the rare earth market. Classification of rare earths 1) Light rare earths (also known as cerium group): lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium. 2) Heavy rare earths (also known as yttrium group): terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, scandium, yttrium. The difference between the cerium group and the yttrium group is that the rare earth mixture obtained by the separation of minerals is often named after the large proportion of cerium or yttrium. Rare earth metals, also known as rare earth elements, is a general term for 17 elements of scandium, yttrium and lanthanum in group III.B of the periodic table, and is often represented by R or RE. Their names and chemical symbols are Scandium (Sc), Yttrium (Y), Lanthanum (La), Cerium (Ce), Praseodymium (Pr), Neodymium (Nd), Promethium (Pm), Samarium (Sm), Europium (Eu), Gadolinium (Gd), Terbium (Tb), Dysprosium (Dy), Holmium (Ho), Erbium (Er), Thulium (Tm), Ytterbium (Yb), Lutetium (Lu). Their atomic numbers are 21 (Sc), 39 (Y), 57 (La) to 71 (Lu). Neodymium (Nd)-doped yvo 4 crystals With its unique position in the field of rare earths, neodymium has become a hot spot in the market for many years. The largest user of neodymium metal is NdFeB permanent magnet material. The advent of NdFeB permanent magnets has injected new vitality and vitality into the high-tech field of rare earths. NdFeB magnets have high magnetic energy accumulation and are known as the "king of permanent magnets" in contemporary times, and are widely used in electronics, machinery and other industries with their excellent performance. The successful development of the alpha magnetic spectrometer marks that the magnetic properties of NdFeB magnets in China have entered the world-class level. Neodymium is also used in non-ferrous metal materials. Adding 1.5~2.5% neodymium to magnesium or aluminum alloy can improve the high-temperature performance, air tightness and corrosion resistance of the alloy, and is widely used as an aerospace material. In addition, neodymium-doped yttrium aluminum garnet produces a short-wave laser beam, which is widely used in industry for welding and cutting thin materials with a thickness of less than 10mm. In medical practice, neodymium-doped yttrium-aluminum garnet lasers are used instead of scalpels for surgical removal or sterilization of wound wounds. Neodymium is also used in the coloring of glass and ceramic materials and as an additive in rubber products. With the development of science and technology, the expansion and extension of the field of rare earth science and technology, neodymium will have a broader utilization space.

Rare earth element praseodymium and its applications
Praseodymium is the third most abundant element in the lanthanide series in the periodic table of chemical elements, with an abundance of 9.5 ppm in the earth's crust, only below cerium, yttrium, lanthanum and scandium, and is the fifth most abundant element in rare earths. In the history of the discovery of rare earth elements, praseodymium and neodymium were discovered at the same time. In 1841, C.G. Mosander, the Swedish chemist who had discovered lanthanum, discovered a new "element" from "lanthanum earth", which was very similar in nature to lanthanum, and named it "Didi."
