在神奇的稀有金属王国里,一些金属元素由于电子结构和理化性质相似,且具有元素对的特征,常常成对地出现在矿物中,如钽和铌、钨和钼等。锆和铪就是这些对中的一对孪生姊妹。锆和铪由于提取方法复杂,产量较少,用途特殊,在日常生活中不像普通有色金属那样被人们熟知,加之熔点高,而 In the magical rare-metal kingdoms, some metal elements are often found in pairs in minerals, such as tantalum and niobium, tungsten and molybdenum because of their similar electronic structure and physicochemical properties, as well as elemental pairs. Zirconium and hafnium are twin pairs of these pairs. Zirconium and hafnium due to complex extraction methods, yield less special purpose, unlike in everyday life are not as common as non-ferrous metals, coupled with high melting point, and
