以四氯化钛为介质离心分离钛同位素

为了实现钛同位素的分离制备，采用气体离心法，开展了以四氯化钛为工作介质的离心分离研究。通过对工作介质四氯化钛的组分分析，开展单机离心分离实验，得到四氯化钛的基本全分离系数达到1.08的单机工况，并在此基础上进行钛同位素的离心分离级联计算，得到矩形级联、相对丰度匹配级联（MARC级联）的设计参数。该研究的开展确定了气体离心法分离钛同位素的可行性，可为气体离心法生产钛同位素产品提供参考。

Centrifugal Separation of Titanium Isotopes Using Titanium Tetrachloride as Processing Gas

Stable isotope techniques have been widely used in modern agriculture, ecological environment, medical diagnosis, nuclear industry, fundamental physics research, and so on. Natural titanium has 5 stable isotopes. ⁴⁸Ti, ⁵⁰Ti and depleted ⁴⁶Ti isotopes respectively have important applications in nutritional studies, fundamental physics research and radioactive therapy. Study on centrifugal separation of titanium isotopes was carried out based on domestic centrifuges, with titanium tetrachloride as processing gas. Single-centrifuge experiments were done. As a result, the single-centrifuge working parameters for titanium tetrachloride were obtained where the basic overall separation factor of it reached 1.08. In addition, numerical calculation of centrifugal cascades for titanium isotopes was performed based on the results above. The design parameters of centrifugal cascades for titanium isotopes production were worked out. The study lays a foundation for titanium isotopes production by gas centrifugation method.
