摘要

Pulsed current electrolysis was applied in NaCl-KCl-MnCl 2 melt at 983 K to enhance morphology ofcathode product. A tungsten wire was used as the working electrode, a carbon rod was employed as thecounter electrode and Ag/AgCl was used as the reference electrode. The electrochemical reduction ofMn 2+ was investigated in this three-electrode cell. Then tungsten wire and carbon rod were used as thecathode and anode to establish a two-electrode cell. Under pulsed current electrolysis, the influence ofvarious pulsed parameters (e.g., periodic time (t) and the ratio of t on to t off (n)) on the morphology ofcathode product was explored. It was found that comparing with that of direct current electrolysis, whent=10 min, n=1, the produced manganese with coarser grain was obtained. In addition, high carbonferromanganese was used as the anode, with a tungsten plate as the cathode to perform pulsed currentelectrorefining. It was also concluded that when t=10 min, n=1, the morphology of produced manganeseand iron was obviously improved, with large grain obtained.
