- Abstract
The vacuum distillation experiment ol In-Sn binary alloy was carried out under the conditions ol system pressure ol 5 --10 Pa and distillation temperature ol 1 470--1 570 K. The results show that the content of In in the liquid phase decreased Irom 14. 31 % to 0, 01 % with the increasing ol distillation temperature, which indicatesthat vacuum distillation can effectively separate In-Sn alloy. The molecular interaction volume model (MIVM) was used to calculate the activity of components of In-Sn alloy. The average standard deviations of the calculated values and the experimental data were i 0. 011 3 and i 0. 015 4, respectively, and the average relative deviations were 土11. 8134% and 土 11* 7322 % »respectively* The results show that the MIVM is reliable for predicting the activity of In-Sn alloy* The Vapor-Liquid Equilibrium (VLE) data of In-Sn alloy was predicted based on the MIVM. A comparison shows that the predicted value is consistent with the experimental data determined in this study, which indicates that the MIVM is reliable for predicting the VLE value of indium-based alloys and can be used to guide the separation of indium-based alloy by vacuum distillation. The reliability of the MIVM model was verified and the process parameters for vacuum distillation separation of indium-based alloys are also optimized based on the model prediction and vacuum distillation experiments. This study may provide guidance for vacuum separation and purification of indium-based alloys or processing of complex materials containing indium.
