Abstract
A device for preparing superfine metal powder with a membrane electrolytic method mainly comprises an electrolytic bath, an anode fluid circulation tank, a cathode fluid circulation tank, a circulating pump and a valve and is characterized in that a cathode chamber and an anode chamber of the electrolytic bath are separated. By adopting an anion-exchange membrane, during the electrolytic preparation process of metal powder, only anions of the cathode chamber can move to the anode chamber through the anion-exchange membrane driven by electric field force, but none of cations of the anode chamber can move to the cathode chamber through the anion-exchange membrane. Therefore, scrap metal can be utilized without having to use high-purity metal. During the electrolytic process, the scrap metal is subjected to electrochemical dissolution at the anode and enters the anode chamber. Then, anode chamber electrolyte is subjected to purification and led to the cathode chamber, and high-purity superfine metal powder is separated out and prepared on a cathode plate. By means of the device, raw materials of high-purity metal may not necessarily be used. In addition, prepared metal powder is high in purity and high in fineness, the technical process is simple, and production cost is greatly lowered.
