铌是高熔点的金属,是重要的合金钢添加剂。它具有抗高温、耐腐蚀和低温超导等一系列优良特性,广泛应用在冶金、化工、电子和宇航等尖端技术部门。六十年代以来,随着微合金钢的开发,铌的用量迅速增大,越来越受到人们的重视,铌的应用不断取得新的进展。 Niobium is a high melting point metal and is an important alloying steel additive. It has a series of excellent features such as high temperature resistance, corrosion resistance and low temperature superconductivity. It is widely used in cutting-edge technology departments such as metallurgy, chemical industry, electronics and aerospace. Since the 1960s, with the development of microalloyed steel, the amount of niobium has been rapidly increasing, attracting more and more people’s attention, and the application of niobium has made new progress.
