稀土元素具有广泛的用途,在大多数的应用中其效果都与原料的纯度、粒度、粒经分布范围等因素有关。由于超微粉末的比表面积大、化学活性高,因此可以预料,若将稀土化合物制成超微粉末,会使它的催化性能及在各种材料中的性能有明显的改变,也可使稀土有新的、更高的应用价值。 Rare earth elements have a wide range of uses, and in most applications their effectiveness is related to the purity, particle size, distribution range of the particles and other factors. Due to the large specific surface area and high chemical activity of the ultrafine powder, it is expected that if the rare earth compound is made into ultrafine powder, its catalytic performance and performance in various materials will be significantly changed, and the rare earth A new, higher value of the application.
