How Many Types of Rare Earth?<\/h2>\n
Las tierras raras se dividen en \"tierras raras ligeras\" y \"tierras raras pesadas\": <\/p>\n <\/p>\n Lantano<\/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 El cerio se utiliza en una amplia gama de campos, incluidas casi todas las aplicaciones de las tierras raras. Por ejemplo, polvo de pulido, material termoel\u00e9ctrico, electrodo de tungsteno de cerio, cer\u00e1mica piezoel\u00e9ctrica, catalizador de gasolina, aleaciones de acero y metales no 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 El \u00f3xido de europio se utiliza sobre todo en f\u00f3sforos.<\/p>\n A. Su complejo paramagn\u00e9tico soluble en agua puede mejorar la se\u00f1al de resonancia magn\u00e9tica del cuerpo humano en el campo m\u00e9dico. 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 El disprosio desempe\u00f1a un papel importante en muchos campos de la alta tecnolog\u00eda, como aditivos para imanes permanentes NdFeB, activadores de f\u00f3sforo, materiales met\u00e1licos necesarios para aleaciones Terfenol, materiales de almacenamiento magneto-\u00f3ptico, absorbedores de neutrones, etc.<\/p>\n El holmio se utiliza como aditivo en las l\u00e1mparas de halogenuros met\u00e1licos, en el granate de itrio-hierro o itrio-aluminio, en la comunicaci\u00f3n por fibra \u00f3ptica y en medicina.<\/p>\n Las propiedades \u00f3pticas del erbio son tan excepcionales que los investigadores le han prestado mucha atenci\u00f3n. La emisi\u00f3n de luz ER3+ a 1550 nm reviste una importancia especial. El r\u00e1pido desarrollo de la comunicaci\u00f3n por fibra \u00f3ptica abrir\u00e1 nuevos campos de aplicaci\u00f3n para 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 El lutecio se utiliza principalmente para <\/p>\n <\/p>\n A\u00f1adir itrio al acero y a las aleaciones no ferrosas puede mejorar notablemente el rendimiento. Las aleaciones que contienen itrio, con un alto contenido de itrio de hasta 90%, pueden utilizarse en la industria aeroespacial y otras aplicaciones que requieren baja densidad y alto punto de fusi\u00f3n. Adem\u00e1s, el itrio tambi\u00e9n se utiliza como material de revestimiento resistente a altas temperaturas, diluyente para el combustible de reactores nucleares, aditivo para materiales magn\u00e9ticos permanentes y getter en la industria electr\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 Enlaces relacionados: Are you facing a mineral processing problem?
