How Many Types of Rare Earth?<\/h2>\n
Les \u00e9l\u00e9ments de terres rares sont divis\u00e9s en \"\u00e9l\u00e9ments de terres rares l\u00e9gers\" et \"\u00e9l\u00e9ments de terres rares lourds\" : <\/p>\n <\/p>\n Lanthane<\/strong> is widely used in piezoelectric materials, electrothermal materials, thermoelectric materials, magnetoresistance materials, luminescent materials, hydrogen storage materials, optical glass, laser materials, all kinds of alloy materials, etc. It is also used as a catalyst for the preparation of many organic chemical products and light conversion agricultural films.<\/p>\n As a glass additive, cerium<\/strong> can absorb ultraviolet and infrared rays; it has been widely used in automobile glass. Not only can it prevent ultraviolet rays, but it can also reduce the temperature in the car, thus saving electricity for air conditioning.<\/p>\n Cerium is now being used as a catalyst for purifying automobile exhaust, effectively preventing a large amount of automobile exhaust from being released into the air. The United States accounts for a third of rare earth consumption in this application.<\/p>\n Cerium sulfide can replace lead, cadmium, and other metals harmful to the environment and human beings to be used in pigments.<\/p>\n Le c\u00e9rium est utilis\u00e9 dans un large \u00e9ventail de domaines, y compris dans presque toutes les applications des terres rares. Il est notamment utilis\u00e9 comme poudre de polissage, mat\u00e9riau thermo\u00e9lectrique, \u00e9lectrode de tungst\u00e8ne au c\u00e9rium, c\u00e9ramique pi\u00e9zo\u00e9lectrique, catalyseur pour l'essence, acier alli\u00e9 et m\u00e9tal non ferreux, etc.<\/p>\n <\/p>\n <\/p>\n Praseodymium is mainly used in glass, ceramics, and magnetic materials. For making permanent magnets, using the cheap praseodymium-neodymium metal to replace the pure neodymium metal to make the permanent magnetic material, its anti-oxygen performance and mechanical performance are improved obviously, and can be processed into various shapes of magnets. Widely used in all kinds of electronic devices and motors. The largest user of the metal neodymium is the neodymium-iron-boron permanent magnet material. The appearance of the Nd-Fe-B permanent magnet has injected new vitality and vigor into the field of rare-earth high-tech. Neodymium is also used in Non-ferrous metal materials. The addition of 1.5 ~ 2.5% neodymium to magnesium or aluminum alloys can improve the high-temperature properties, gas tightness, and corrosion resistance of the alloys, and is widely used as aerospace materials. In addition, neodymium also has a great influence on medicine, glass, ceramics, and rubber products.<\/p>\n Promethium is an artificial radioactive element from a nuclear reactor. The primary uses of promethium are (1) as a heat source. To provide auxiliary power for vacuum detection and satellites. (2) PM 147 emits low-energy radiation to make promethium batteries.<\/p>\n <\/p>\n <\/p>\n Samarium is the raw material for making samarium-cobalt permanent magnets. Samarium-cobalt magnets are the first rare-earth magnets to be used in the industry.<\/p>\n L'oxyde d'europium est principalement utilis\u00e9 dans les luminophores.<\/p>\n A. Son complexe paramagn\u00e9tique soluble dans l'eau peut am\u00e9liorer le signal d'imagerie par r\u00e9sonance magn\u00e9tique du corps humain dans le domaine m\u00e9dical. The terbium element is mainly used as an activator of green powder in fluorescent powder, magneto-optical storage material, magneto-optical glass, sonar, regulating mechanism of space telescope, aircraft wing regulator, and so on.<\/p>\n <\/p>\n <\/p>\n Le dysprosium joue un r\u00f4le important dans de nombreux domaines de haute technologie, tels que les additifs pour les aimants permanents NdFeB, les activateurs de phosphore, les mat\u00e9riaux m\u00e9talliques n\u00e9cessaires pour les alliages Terfenol, les mat\u00e9riaux de stockage magn\u00e9to-optique, les absorbeurs de neutrons, etc.<\/p>\n L'holmium est utilis\u00e9 comme additif dans les lampes aux halog\u00e9nures m\u00e9talliques, dans le grenat d'yttrium-fer ou d'yttrium-aluminium, dans les communications par fibre optique et en m\u00e9decine.<\/p>\n Les propri\u00e9t\u00e9s optiques de l'erbium sont si exceptionnelles que les chercheurs lui ont accord\u00e9 une grande attention. L'\u00e9mission de lumi\u00e8re ER3 + \u00e0 1550 nm est particuli\u00e8rement importante. Le d\u00e9veloppement rapide de la communication par fibre optique ouvrira de nouveaux champs d'application pour ER3 +.<\/p>\n <\/p>\n <\/p>\n Thulium can be used as a radiation source for portable medical X-ray machines, and can also be applied in clinical diagnosis and treatment of tumors, reducing the radiation and harm of X-rays to humans, which has important practical significance in medical applications.<\/p>\n A ytterbium-gadolinium gallium garnet embedded line waveguide laser has been successfully prepared by Japanese scholars, which is of great significance to the further development of laser technology. Ytterbium is also used as a phosphor activator, radio ceramic, computer memory element additive, glass fiber flux, and optical glass additive.<\/p>\n Le lut\u00e9cium est principalement utilis\u00e9 pour <\/p>\n <\/p>\n L'ajout d'yttrium \u00e0 l'acier et aux alliages non ferreux peut am\u00e9liorer consid\u00e9rablement les performances. Les alliages contenant de l'yttrium avec une teneur \u00e9lev\u00e9e en yttrium (jusqu'\u00e0 90%) peuvent \u00eatre utilis\u00e9s dans l'a\u00e9rospatiale et d'autres applications n\u00e9cessitant une faible densit\u00e9 et un point de fusion \u00e9lev\u00e9. En outre, l'yttrium est \u00e9galement utilis\u00e9 comme mat\u00e9riau de rev\u00eatement r\u00e9sistant aux hautes temp\u00e9ratures, comme diluant pour le combustible des r\u00e9acteurs nucl\u00e9aires, comme additif pour les mat\u00e9riaux magn\u00e9tiques permanents, et comme getter dans l'industrie \u00e9lectronique.<\/p>\n In the electronics industry, scandium can be used as a semiconductor device, in the chemical industry, as an alcohol dehydrogenation and dehydrating agent, to produce ethylene, and to produce chlorine from waste hydrochloric acid. In the glass industry, it is possible to make special glasses containing scandium. In the electric light source industry, the sodium lamp made of scandium and sodium has the advantages of high efficiency and positive color. In medicine, 46Sc is used to treat cancer.<\/p>\n Rare Earth metals have been widely used in electronics, petrochemicals, metallurgy, machinery, energy, light industry, environmental protection, agriculture, and other fields. Rare Earth can be used to produce fluorescent materials, rare earth hydride battery materials, electric light source materials, permanent magnetic materials, hydrogen storage materials, catalytic materials, precision ceramic materials, laser materials, Superconductor classification materials, magnetostrictive materials, magnetic refrigeration materials, magneto-optical storage materials, optical fiber materials, etc.<\/p>\n Liens connexes : Are you facing a mineral processing problem?
