摘要
采用二次蒸馏后铸锭的方法获得了氧含量低于300×10-6的高纯金属铕,用双层包装,内外包装都充氩气,外层内加稀土吸气剂,在储存和运输过程中,包装的金属铕不会氧化。采用此方法,可实现批量生产。
High-purity europium metal containing less than 300 ×10^-6 oxygen can be obtained by 2-step distillation and ingot casting. 2-layer packing is applied filled with Ar and with RE degasser in the exterior layer to avoid oxidization of europium metal during storage and transportation to ensure batch production.
