<p>PURPOSE:To manufacture ductile electrolytic iron foil at high current density by using an iron chloride soln. contg, ferrous ions at high concn. as an electrolytic soln. and by electrodepositing iron in the presence of an insoluble anode while adjusting the amount of free hydrochloric acid in the electrolytic soln. CONSTITUTION:Iron is electrodeposited on a substrate for electroforming in the presence of an insoluble anode, and by stripping the electrodeposited iron layer, electrolytic iron foil is manufactured. At this time, an iron chloride soln. contg. 200-400g/l ferrous ions is used as an electrolytic soln., and while adjusting the amount of free hydrochloric acid in the electrolytic soln. to 2-60g/l, iron is electrodeposited at 90-120 deg.C. Long-sized electrolytic iron foil can be manufactured easily and continuously without separating an electrolytic soln. between anode and cathode unlike a diaphragm or laminar flow method, and ductile iron foil can be obtd. even at increased current density.</p> |
