چکیده انگلیسی
Activity coefficients of Pb-Sn alloy with different Pb contents at 777 °C were calculated with molecular interaction volume model, which agree well with the available experimental values. Activity coefficients at 800-1300 °C were predicted to supply valuable data for thermodynamic calculation of vacuum distillation. Small-scale and continuous industrialized experiments of vacuum distillation for two different components of Pb-Sn alloys were performed and the lead content in refined tin was decreased to less than 0.01% successfully. Vacuum distillation treatment of Pb-Sn alloy in which lead content fluctuated from 10% to 90% was put forward. The final product is crude lead with purity above 99.5% and refined tin with lead content less than 0.01%.
