Problems solved by technology

According to the inventor's analysis, the qualified nickel is likely to come from the platinum lead, because most of the platinum comes from the residue of nickel smelting, and it is not surprising that platinum contains a small amount of nickel. Pure gallium is also very impure
At the same time, platinum electrode leads are used, which takes up more funds and increases production costs

Embodiment 1

[0013] Embodiment 1: as figure 1 As shown, in the electrolytic cell used for the electrolysis of gallium, the anode electrode area 1 and the cathode electrode area 6 are separated by the electrode area separator 7, and gallium to be electrolytically purified and refined gallium are respectively placed in the anode electrode area 1 and the cathode electrode area 6. The cathode and anode electrode wires are respectively inserted into the solution 2, and the electrode wires are made of solid metal gallium 4, and a cooling device 5 is provided outside the solid metal gallium 4, and the cooling device 5 cools the solid metal gallium 4 through the circulating flow of cooling liquid to maintain the form of solid gallium , because the melting point of metal gallium is 30°C, so the solid gallium lead which is in contact with the liquid gallium electrode at 50°C during electrolysis must be kept in a strong freezing environment for a long time, so that the temperature of the solid gallium...

Abstract

The invention discloses an electrode lead wire used in the process of gallium metal electrolysis, which is made of solid gallium metal, wherein a lead wire of the solid gallium metal is provided with a cooling device which is a cooling fluid circulating cooling device. The design uses the solid gallium metal as the lead wire of a liquid gallium electrode to solve the problem that the liquid gallium erodes various metal material lead wires; and with the solid gallium metal lead wire, the pollution caused by nickel to refined gallium is thoroughly eliminated. While greatly improving the electrolysis refining effect, the electrode lead wire greatly reduces the production cost and reduces the consumption of noble metals such as platinum.

Description

technical field [0001] The invention relates to an electrolysis electrode lead, in particular to an electrode lead used in the electrolysis of gallium metal. Background technique [0002] When gallium is electrolytically refined, due to the low melting point of gallium, whether it is raw gallium or refined gallium, it is in a liquid state in the electrolytic tank. The introduction of electrolytic current must find a suitable material, otherwise the refined gallium will be seriously polluted, because liquid gallium It is highly corrosive to various metals. [0003] A common method is to introduce another material as its electrode lead. When stainless steel is used as the electrode lead, nickel-chromium stainless steel is mostly used, so it is easy to introduce other impurities during the electrolysis process. Usually electrolytic gallium uses metal platinum as the lead, but it is often mistaken for platinum as the electrolytic electrode. Although platinum can also be used a...
