一、稀土近况和预测稀土化合物、稀土金属、稀土合金具有特殊的性能,因而在冶金、石油化工、电子、航天、原子能,轻工业以及玻璃陶瓷、医药卫生、农业等领域,得到广泛应用,特别是随着荧光、磁性、激光、光纤通讯、贮氢能源、超导等新技术的发展,需要大量稀土原料,稀土开发,大有可为。稀土工业的出路,在于搞深度加工和应用,美国稀土新兴应用的开发研究和新技术推广应用,处于领先地位,第三代稀土永磁材料Nd—Fe—B的问世,估计欧美市场仅稀土永磁材料产值近2.5亿美元,预计在十几年内将有很大发展,1995年欧美磁体产值将达到25亿美元,其中Nd—Fe—磁体就达到10亿美元。日本稀土工业发展迅速,原科靠进口,建立稀土冶炼分离厂,致力于产品研究和深加工。
First, the status of rare earth and the prediction Rare earth compounds, rare earth metals, rare earth alloys with special properties, and therefore in metallurgy, petrochemicals, electronics, aerospace, atomic energy, light industry and glass ceramics, medicine and health, agriculture and other fields, especially With the development of new technologies such as fluorescence, magnetism, laser, optical fiber communication, hydrogen storage energy and superconductivity, a large amount of rare earth raw materials and rare earths are needed for development. Rare earth industry way lies in engaging in deep processing and application, the development and application of new rare earth US applications and new technologies to promote the application of a leading position, the third generation of rare earth permanent magnet material Nd-Fe-B advent, estimated that European and American markets only rare earth forever The output value of magnetic materials is nearly 250 million U.S. dollars. It is estimated that there will be a great development within a decade. In 1995, the output value of magnetism in Europe and the United States will reach 2.5 billion U.S. dollars, of which Nd-Fe-magnets will reach 1 billion U.S. dollars. Japan’s rapid development of rare earth industry, the original subjects by the import, the establishment of rare earth smelting separation plant, is committed to product research and deep processing.
