稀土虽然其名称为稀土,其实在自然界中并不稀少。例如,我们知道地壳中含有大量的天然镧系元素,其含量可与铜元素相比。由于稀土具有的一些特殊性能,使其在催化剂材料、辉光、光学、磁学、电子等众多领域中得到广泛的应用。Rhodia公司长期致力于稀土材料的研究,并开发出一系列稀土产品,下面择其主要产品作一简介: Rare earth although its name is rare earth, in fact, not rare in nature. For example, we know that the earth’s crust contains a large amount of natural lanthanides, which can be compared with copper. Due to the rare earth has some special properties, it has been widely used in catalyst materials, glow, optics, magnetism, electronics and many other fields. Rhodia company has long been committed to the study of rare earth materials and the development of a series of rare earth products, following the main product to make a profile:
