Abstract: An apparatus and method for preparing high-purity spherical magnesium and/or high-purity magnesium powder are provided. The apparatus includes a vertical furnace body, a heating zone, and a condensing zone, where a periphery of the condensing zone is provided with a first thermal insulation device and a second thermal insulation device sequentially from bottom to top, and each of the first thermal insulation device and the second thermal insulation device is removably arranged; the periphery of the condensing zone is further provided with a liquid cooling device; a gas inlet and a gas outlet are formed in the condensing zone; and an inner wall of the condensing zone is provided with an arrangement structure configured to arrange a collection device. A heating temperature of a material and condensation conditions in the condensing zone are controlled to make an evaporated magnesium vapor condensed on the collection device in the condensing zone.

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.
