Abstract: A device is provided for fractional condensation of an arsenic-lead vapor mixture and an application method thereof. The device includes a vacuumizing device, a flange, temperature measuring devices, a graded vacuum furnace body, a quartz tube, a push rod, a control cabinet, a heating zone and recycled foil. The length of the quartz tube is 1.2-2 m; the length of the heating zone is 0.15-0.25 m; and the quartz tube is provided with one temperature measuring device every 2-3 cm. The device forms a certain temperature gradient in the quartz tube, so that a material condenses in the corresponding temperature range, thereby achieving the purpose of high-efficiency separation.
