铀是核军工的基石,也是重要的核能原料。由于它的不稳定性和变价性,长期以来,人们认为在自然界没有金属铀,目前工业上的金属铀系也是通过四氟化铀(UF4)的钙(镁)金属热还原法来制备的。幸运的是,中国科研人员打破了这一束缚人类多年的禁锢,首先在自然界中发现金属铀。核工业北京地质研究院院长李 Uranium is the cornerstone of the nuclear industry and an important source of nuclear energy. Due to its instability and variability, it has long been assumed that there is no metallic uranium in nature and that the current industrial uranium series is also prepared by the calcium (magnesium) metal thermal reduction of uranium tetrafluoride (UF4). Fortunately, Chinese researchers have broken this bondage that has bound humanity for many years. First, they found metal uranium in nature. Nuclear Industry Beijing Institute of Geology Li
