The rare earth element itself has a rich electronic structure and exhibits many optical, electrical and magnetic properties. After nano-roughing, it exhibits many characteristics, such as small size effect, high specific surface effect, quantum effect, strong light, electricity, magnetic properties, superconductivity, high chemical activity, etc., which can greatly improve the performance and function of materials. , developed many new materials. It will play an important role in high-tech fields such as optical materials, luminescent materials, crystalline materials, magnetic materials, battery materials, electronic ceramics, engineering ceramics, and catalysts. Current research and application areas First, rare earth luminescent materials: rare earth nano phosphors (color powder, lamp powder), luminous efficiency, will greatly reduce the amount of rare earth. Mainly used are Y 2 O 3 , Eu 2 O 3 , Tb 4 O 7 , CeO 2 , and Gd 2 O 3 . New candidate materials for high definition color TVs. Second, nano-superconducting materials: YBCO superconductors prepared by using Y 2 O 3 , special film materials, stable performance, high strength, easy processing, close to the practical stage, broad prospects. Third, rare earth nano magnetic materials: for magnetic memory, magnetic fluid, giant magnetoresistance, etc., the performance is greatly improved, so that the device becomes high performance and miniaturization. Such as oxide giant magnetoresistance target (REMnO 3, etc.). 4. Rare-earth high-performance ceramics: electronic ceramics (electronic sensors, PTC materials, microwave materials, capacitors, etc.) prepared using ultrafine or nanoscale Y 2 O 3 , La 2 O 3 , Nd 2 O 3 , Sm 2 O 3 , etc. Thermistors, etc., have many improvements in electrical properties, thermal properties, and stability, and are important aspects of electronic material upgrades. For example, ceramics sintered at a lower temperature such as nanometer Y 2 O 3 and ZrO 2 have strong strength and toughness, and are used for wear-resistant devices such as bearings and cutters; and are made of nano Nd 2 O 3 , Sm 2 O 3 , etc. Layer capacitors and microwave devices have greatly improved performance. 5. Rare Earth Nanocatalysts: In many chemical reactions, rare earth catalysts are used. If rare earth nanocatalysts are used, the catalytic activity and catalytic efficiency will be greatly improved. CeO 2 nano powder active in automobile exhaust purifier, having a high activity, low price, the advantages of long lifetime, and replace most of the noble metal, the amount of thousands of tons per year. Sixth, rare earth UV absorber: Nano CeO 2 powder is very strong for UV absorption, used in sunscreen cosmetics, sunscreen fiber, automotive glass and so on. Seven, rare earth precision polishing: CeO 2 has a good polishing effect on glass. Nano-CeO 2 has high polishing precision and has been used in liquid crystal display, silicon single wafer, glass storage and the like. In short, the application of rare earth nanomaterials has just begun, and it is concentrated in the field of high-tech new materials, with high added value, wide application, great potential, and very promising business prospects.
