| Abstract: | Materials containing Cadmium and Thallium are evaporated on the condition that the temperature is 400 -700℃and remaining pressure is 10 -60 Pa. Through chemical determination of Cadmium and Thallium, calculation of activity coefficients and fitting of the experimental data, the relationships among activity coefficients, temperature and composition are obtained, which provides a theoretical basis for separating Cadmium and Thallium by vacuum metallurgy distillation. |
| Keywords: | vacuum distillation Cadmium Thallium activity coefficient |
