| abstract | PURPOSE:To produce extremely high-quality In by electrolytically refining crude In as a consumable anode in a diaphragm cell with an aq. soln. of InClx as the electrolyte, heating, and melting the In deposited on a cathode along with a chlorinating agent. CONSTITUTION:An aq. soln. contg. 100-300g/l indium chloride adjusted to 0.5-2.0pH is used as the electrolyte, and crude In contg. <10ppm Cd and <1ppm Tl as a consumable anode is electrolyzed at 0.5-2A/dm<2> cathode current density in the diaphragm cell using natural fibers such as cotton or synthetic fibers such as PE as the diaphragm to deposit high-purity In on the cathode. The electrolyte discharged from the anode chamber during the electrolytic refining is filtered to remove suspended slime, successively brough into contact with an anion-exchange resin to remove Ag, Bi, and other impurities, then returned to the cathode chamber, and electrolyzed. The In deposited on the cathode is released from the cathode, heated, and melted along with a chloride such as ammonium chloride to remove the remaining impurities in the In as the chloride. Consequently, In having >=99.9999% purity can be produced. |
