铀标准溶液制备

如图所示钙还原UF₄、NpF₄、PuF₄制备金属

单质的钢弹还原容器

(最大容器用作2.5kg的批量制备)

采用钢弹还原技术，用钙还原铀的氟化物(UF₄)并用碘作为促进剂（增压器）可得到致密的金属铀熔渣。每摩尔铀需要加入约0.15mol碘来促进反应，钙金属过量约25%，所设计的反应装置如图所示。所有还原容器的交叉部分规模都趋向一致。最小的容器用于制备1g量的金属，产率＞95%，最大的容器用于批量制备2.5kg量的金属，产率＞99%。将氟化铀与粒状的钙和碘混合，倒进大小合适的还原容器中，所用容器是由一个不锈钢质且用镁砂作内衬的耐压容器组成，内衬可以是单个的低密度坩埚，在大装置中也可以是一个在环形空间中填充上镁砂的小一点的坩埚。在装上反应物以后，盖上盖子，抽空容器，再充上氩气，密封气体接口，给环形线圈接上10kHz的感应加热容器。加热后，倾出容器内的物质，打碎坩埚，机械分离金属熔渣和炉渣。
