Abstract

公开了高纯度铌金属和含有该铌金属的合金。所述铌金属优选具有的纯度至少为99.99％，更优选至少为99.999％。而且，公开了铌金属及其合金，它们具有的粒度约150微米或更低；或具有这样一种结构，其在厚度的5％增量内的(100)强度是低于约30随机；或(111)∶(100)强度的增量对数比值大于约－4.0；或这些特性的任意组合。还公开了由所述铌金属制成的制品和元件，包括但不限于这些：溅射靶、电容器罐、电阻膜层、电线等。还公开了一种用于制备所述高纯度铌金属的方法，它包括在一个反应容器中使一种含铌盐和一种金属盐以及至少一种能够还原所述含铌盐的化合物进行反应的步骤。所述反应容器或反应容器内的内衬和所述搅拌器或搅拌器上的内衬，是由一种与熔化的铌具有相同或更高蒸气压的金属材料制成的。所述高纯度铌产品优选具有一种精细和均匀的微结构。

English (machine translation): High purity niobium metals and alloys containing the same are described. The niobium metal preferably has a purity of at least 99.99 % and more preferably at least 99.999 %. In addition, niobium metal and alloys thereof are described, which either have a grain size of about 150 microns or less, or a texture in which a (100) intensity within any 5 % increment of thickness is less than about 30 random, or an incremental log ratio of (111):(100) intensity of greater than about -4.0, or any combination of these properties.…
