摘　　要：在氩气保护下,以DyF3为萃取剂采用熔盐萃取法制备低氧金属镝的新工艺,可使金属镝中氧、钙含量大幅度降低,为工业规模化生产低氧、低钙金属镝提供了新的途径。Under the condition of argon gas, the new technology about preparation of hypoxia dysprosium metal by fusedsalt extraction method with DyF3 as extracted agent can widely reduce oxygen and calcium content in dysprosium metal. The new way of hypoxia and hypocalcia dysprosium metal produced industrialization was proposed.
