and alloys 2.1 Vacuum distillation and separation of Pb-Sn alloys In 1977, the continuous inner heating and multiple-stage vacuum furnace hand led solders[1,2,5], according to the difference.... The vacuum distillation of Pb-Sn alloys is a physical process, which vaporizes Pb and remains Sn, th e Pb vapor condenses into liquid Pb, so metal Sn and Pb can be produced direct ly. The success of vacuum......
