Abstract: Provided is a method for preparing high-purity indium (In). The method for preparing the high-purity In includes: distilling refined In to obtain an In vapor-containing gas; and condensing the In vapor-containing gas to obtain the high-purity In; where the distilling is conducted at a temperature of 1,000° C. to 1,100° C. under a vacuum degree of 1.0×10−3 Pa to 5.0×10−2 Pa; and the condensing is conducted at a temperature of 700° C. to 900° C. under a vacuum degree of 1.0×10−3 Pa to 5.0×10−2 Pa. The In vapor-containing gas is obtained by controlling the temperature and vacuum degree of the distilling to evaporate In and impurities with a vapor pressure higher than the In. The temperature and vacuum degree of the condensing are adjusted to condense the In in the In vapor-containing gas.

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.
