1842年，Peligot（14岁）首次尝试制备金属铀，他在一个上釉的陶瓷坩埚中用钠还原了氯化铀。钠被一层干燥的氯化钾和氯化铀覆盖，反应通过从外部加热坩埚开始。Zimmerman（16）的方法与之相似，只是用氯化钠代替氯化钾来覆盖混合物。根据Moissan（10）的说法，这种方法产生的粉末被少量的钠和组合氮污染。莫瓦桑使用了更稳定的双盐UCL^ NaCl，在一个封闭的铁管中与钠一起加热。Moissan（11）还尝试在电炉中用糖炭还原氧化铀（UsOs），并获得了一种含有一些碳和其他杂质的金属。Aloy(1)用糖炭-煤还原氧化物UO2，所得产物被碳污染。用铝对UO2的还原也进行了研究
THE first attempt to prepare metallic ura-nium was made in 1842 by Peligot (14), who reduced uranium chloride by means of sodium in a glazed por-celain crucible. The sodium was covered with layers of dry potassium chloride and uranium chloride and the re-action was started by heat-ing the crucible externally. Zimmerman’s (16) method was similar except that sodium chloride was substi-tuted for the potassium chloride in covering the mixture. According to Moissan (10) this method yields a powder which is contaminated with small amounts of sodium as well as combined nitrogen. Moissan used the more stable double salt UCL^ NaCl, which was heated with sodium in a closed iron tube.Moissan (11) also attempted the reduction of uranium oxide (UsOs) with sugar charcoal in an electric furnace and obtained a metal containing some carbon and otherimpurities. Aloy (1) reduced the oxide UO2 with sugar char-coal, the resulting product being contaminated with carbon. The reduction of UO2 by means of aluminum has also been
