Embodiment

[0035] A vacuum distillation device for indium, mainly used for distillation and purification of metal indium, but it should be noted that this device is only more suitable for distillation and purification of metal indium, it does not mean that the device can only be used for the purification of indium , which can also be used for the purification of other types of molten metal. The specific structure and working principle of the device will be described in detail below.

[0036] Such as figure 1 As shown, the distillation device includes an upper distillation unit, a lower distillation unit and a liquid riser 3 connecting the two distillation units. Wherein, the upper distillation unit includes an upper vacuum chamber 1, in which a crucible 11 and an upper heating device 12 for heating the crucible 11 are arranged, and an upper condensing device 13 is arranged in the upper end of the crucible 11.

[0037] The lower distillation unit is located below the upper vacuum chambe...

Abstract

The invention discloses a vacuum distillation device for indium and a distillation method thereof, and belongs to the field of metal purification. The device comprises an upper vacuum chamber, a container and a riser tube, a crucible and an upper heating device used for heating the crucible are arranged in the upper vacuum chamber, an upper condensing device is arranged at the upper end in the crucible, the container is arranged below the upper vacuum chamber and provided with an air inlet, the air inlet is externally connected with an air inlet device, the lower end face of the crucible is a conical surface, and two ends of the riser tube are respectively communicated with the crucible and the container. According to the method, the distillation device is adopted, the metal indium liquid can be continuously and efficiently purified, and the indium purification efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of metal purification, and more specifically relates to a vacuum distillation device and a distillation method for indium. Background technique [0002] As a rare and precious metal, indium is widely used in the electronics and semiconductor industries for its excellent physical, chemical and mechanical properties. However, the electronics industry and the semiconductor industry have extremely high requirements on the purity of the raw material indium metal, and the introduction of trace impurities will seriously affect the performance of the final device material itself. At present, the main preparation methods of high-purity indium include electrolysis, vacuum distillation, regional smelting, metal-organic compound method, and low-halogen compound method. Due to their unique advantages, these methods have their own suitable application scenarios. In actual production, multiple methods are often combined ...
