How Many Types of Rare Earth?<\/h2>\n
Os elementos de terras raras dividem-se em \"elementos de terras raras leves\" e \"elementos de terras raras pesados\": <\/p>\n <\/p>\n Lant\u00e2nio<\/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 O c\u00e9rio \u00e9 utilizado numa vasta gama de dom\u00ednios, incluindo quase todas as aplica\u00e7\u00f5es de terras raras. Tal como p\u00f3 de polimento, material termoel\u00e9trico, el\u00e9trodo de tungst\u00e9nio de c\u00e9rio, cer\u00e2mica piezoel\u00e9ctrica, catalisador de gasolina, ligas de a\u00e7o e metais n\u00e3o ferrosos, 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 O \u00f3xido de eur\u00f3pio \u00e9 utilizado principalmente em f\u00f3sforos.<\/p>\n A.

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 O dispr\u00f3sio desempenha um papel importante em muitos dom\u00ednios de alta tecnologia, tais como aditivos para \u00edmanes permanentes NdFeB, activadores de f\u00f3sforo, materiais met\u00e1licos necess\u00e1rios para ligas de terfenol, materiais de armazenamento magneto-\u00f3tico, absorventes de neutr\u00f5es, etc.<\/p>\n O h\u00f3lmio \u00e9 utilizado como aditivo em l\u00e2mpadas de halogenetos met\u00e1licos, em granadas de \u00edtrio-ferro ou \u00edtrio-alum\u00ednio, em comunica\u00e7\u00f5es por fibra \u00f3tica e em medicina.<\/p>\n As propriedades \u00f3pticas do \u00e9rbio s\u00e3o t\u00e3o not\u00e1veis que os investigadores t\u00eam-lhe prestado muita aten\u00e7\u00e3o. A emiss\u00e3o de luz do ER3+ a 1550nm \u00e9 de especial import\u00e2ncia. O r\u00e1pido desenvolvimento das comunica\u00e7\u00f5es por fibra \u00f3tica abrir\u00e1 novos campos de aplica\u00e7\u00e3o para o 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 O lut\u00e9cio \u00e9 utilizado principalmente para <\/p>\n <\/p>\n A adi\u00e7\u00e3o de \u00edtrio ao a\u00e7o e \u00e0s ligas n\u00e3o ferrosas pode melhorar significativamente o desempenho. As ligas que cont\u00eam \u00edtrio com um elevado teor de \u00edtrio, at\u00e9 90%, podem ser utilizadas na ind\u00fastria aeroespacial e noutras aplica\u00e7\u00f5es que exijam baixa densidade e elevado ponto de fus\u00e3o. Al\u00e9m disso, o \u00edtrio \u00e9 tamb\u00e9m utilizado como material de revestimento resistente a altas temperaturas, como diluente para combust\u00edvel de reactores nucleares, como aditivo para materiais magn\u00e9ticos permanentes e como getter na ind\u00fastria eletr\u00f3nica.<\/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 Liga\u00e7\u00f5es relacionadas: Are you facing a mineral processing problem?
