The Principle of Refined Cd Vacuum Distillation
The temperature requires 761K of the Cd to reach the 1.33*10³Pa vapor pressure in the vacuum environment, and 888K to reach the 1.33*104Pa vapor pressure. The low-boiling point of Cd liquid is heated and vaporized in the crucible, the vapor separates from the liquid surface and flows to the top where the vapor saturation is lower, when passing through the reflux tray, the metallic vapor that boiling point higher than the Cd and part of Cd vapor would be condensed and return to the crucible, and most of the low-boiling Cd vapor would be condensed to the refined Cd liquid(99.995%) in the inside of the condenser that above the reflux tray.
