Rare earth new materials and their application in high-tech fields. Abstract: This paper briefly describes the new rare earth materials and their application in high-tech fields, and a brief analysis that China's rare earth industry the level of high-tech applications, as well as the development of new rare earth materials and their application of technology in the field of high technology is the fundamental way to achieve the conversion of the rare earth resource advantages into economic advantages. Key words: Key words: rare earth; rare earth new materials; unique physical and chemical properties of high-tech application of rare earth elements, the decision they have an extremely wide range of uses. The china laser pointer company is always positively searching the new technology of china laser pointer.
Rare earth elements has a unique structure of the 4f electrons, the atomic magnetic moment, a strong spin-orbit coupling and other characteristics of the formation of rare earth complexes with other elements, the coordination number of 3 to 12 varies between, and rare-earth compounds The crystal structure is diversified. In the field of new materials, rare earth elements in the optical, electrical, and magnetic properties has been widely applied. In the high-tech fields, rare earth new materials play an important role. The new rare earth materials, including rare earth permanent magnet materials, luminescent materials, rare earth hydrogen storage materials, rare earth catalyst materials, rare earth, ceramic materials, and other rare earth new materials such as rare earth giant magnetostrictive material, giant magnetoresistive materials and magnetic refrigeration materials, light refrigerant materials, magneto-optical storage materials. china laser pointer can be divided into the following as per quantity of laser heads.
Rare earth permanent magnet materials, rare earth permanent magnet materials because of their alloy composition, can be divided into three categories [1]: (1) rare earth - cobalt permanent magnet material: SmCo5, of Sm2Co17; (2) rare earth - iron permanent magnet materials: of Nd2Fe14B; (3) rare-earth iron nitrogen (RE-Fe-N lines) or rare-earth iron-carbon (RE-Fe-C system) permanent magnet materials. Can be divided into chronological order by the development and application of the first generation (1:5 SmCo5), the second generation (2:7 type of Sm2Co17), the third generation (NdFeB), currently being actively developed to find a fourth-generation rare earth permanent magnet. Sm2Co17 has high magnetic properties and stability of a wide range of applications. Nd2Fe14B type rare earth permanent magnet in the 1980s come out, because of its superior performance and lower prices in many areas soon replace Sm2Co17 rare earth permanent magnets, and soon realized industrial production. This type of china laser pointer has the full power of 100mW.
Japan has developed energy product 55.8MGOe of Nd2Fe14B-type rare earth permanent magnet. NdFeB magnets are widely used in energy, transportation, machinery, medical, computer, household appliances and other fields. China NdFeB production in 1998 accounted for 38% of world production, a total of 3850 tons. China NdFeB industry has not yet formed a large-scale operations, products and more affordable products, the energy product is generally less than 45MGOe, mostly 40MGOe the following products, and thus used for audio equipment, the middle and low areas of the magnetization, magnetic separator, etc.; Japan NdFeB production is focused only on a few manufacturers, their products mostly above products 40MGOe, used for computer VCM, the new motor, MRI and other high-tech fields. NdFeB industry only to achieve economies of scale, the industry group, high-performance product quality, can be in an invincible position in international competition, and promote the development of rare earth industry. The good green laser pointer company has the complete testing equipment of good quality so that the product quality is good enough.
The luminescence of rare earth and the advantages of laser materials, luminescent materials is the strong absorptive capacity, the conversion rate, and can be fired from the ultraviolet to the infrared spectrum in the visible region, there is a strong launch capability, and physical and chemical properties and stability. Luminescent materials because of their excitation mechanism can be divided into cathode-ray of rare earth luminescent materials, rare earth photoluminescence materials, X-ray luminescent materials, rare earth scintillator conversion of light-emitting materials and other rare earth functional, rare earth luminescent materials. At present, the luminescent materials used in color TV picture tubes, computer monitors, lighting, medical equipment and other aspects. The rare earth luminescent materials, the largest amount of color TV picture tubes, computer monitors, rare earth tricolor energy saving lamps, PDP plasma display. Luminescent materials for color television picture tubes and computer monitors use a cathode-ray luminous materials. Passing rate of china laser pointer quality can keep above 99.37% for a long time.
