补充资料：氦稳定同位素分离
分子式：
CAS号：
性质：极低温下，液体4He有超流动性，而3He没有，可利用这一特性来分离氦同位素。将3He和4He低温混合液冷却到λ点以下，液体4He转为超流动的4HeⅡ，它沿着杜瓦瓶的外壁自动“爬”入分离容器内，加热“爬”入容器内的4He到λ点以上，失去超流性实现3He和4He的分离。此法与精馏法结合，获得99.995%的3He。也可以热扩散法分离，分离系数(r为热扩散常数0.059)。原料氦引入同心管热扩散柱内，内壁加热，外壁冷却，热壁与冷壁间形成一个同位素浓度梯度，热扩散效应使3He富集于热壁，沿壁上升，浓集于柱顶。4He富集于冷壁，沿壁下流，浓集于柱底。该法不宜富集3He浓度很低的天然氦中的3He。要制取99.6%或更高浓度的3He，需要把几根热扩散柱串联或并联起来使用。热扩散法还可将氦中O2、CO、CO2、H2O等除到10-6以下。
