Concentration and Application of Common Stable Isotopes Preparation

China Institute of Atomic Energy(CIAE) has accomplished state science and technology support plan topic《research and development of high purity organic reagent corn unit using for research and commonness key technology》. ⁵⁴Fe、⁶⁵Cu、⁶⁴Zn、⁶⁷Zn、²⁰⁷Pb and ⁸⁵Rb、⁸⁷Rb were separated using electromagnetic method. And the abundances of them archived: 90%, 99.6%, 96%, 81%, 90%, 99% and 98%. The level of these isotopes preparation has reached overseas product standard. Some of them have been used in the production of science research and rubidium clock production for satellite navigation. It established technology base for material domestic production of special stable isotopes in China.
