Abstract: Provided are a vacuum distillation furnace, and a method for preparing high-purity copper particles. In view of the fact that high-purity copper prepared by the traditional method in the current industrial production has an unsatisfactory purity, a high impurity content, and a complicated composition, a vacuum distillation method is adopted. During the vacuum distillation method, most of valuable metals in a copper matrix are volatilized and enter into a gas phase, such that the metals are separated from the copper matrix, thereby allowing the purification of copper; and copper powder particles volatilized to a condensation plate have a smooth surface and a purity of 5 N grade or more.
