“…Experiments have indicated that the disproportionation reaction is quantitative. Since both Cd and Zn are more negative than In in the electromotive series (3,16), the presence of CdCI~ and ZnCI~ in the fused salt bath does not interfere with the reaction in any way; the resulting In metal is spectroscopically free of Cd and of Zn.…”

A fused salt bath for electrodeposition of molten cadmium ‐indium alloy is described, from which ellipsoidal beads of molten alloy are plated onto wires used as leads to emitter and collector electrodes of transistors. Electrodeposition of molten metals can be very rapid, and the deposits are smooth, dense, and nonporous. The fused salt bath, containing 6% cadmium chloride, 56% indium monochloride, and 38% zinc chloride, by weight, is operated at about 260°C. Tungsten anodes are used. With 6 v d.c. applied, a 2 mg ellipsoidal bead of cadmium ‐indium alloy of approximately eutectic composition can be deposited on a 0.5 mm wire that is immersed a depth of 1.5 mm into the plating bath in about 4 sec. Under these conditions, current density is of the order of 40 amp/cm2. The effect of bath composition and of plating conditions on alloy composition and plating rate is discussed.

“…This subject has been treated by others (2). The tendency of compounds of indium to be relatively nonionic or covalent in their bonding is felt to be one of the more important properties of this element which influences its metallurgy.…”

Metallurgical operations on products containing indium result in its concentration in a slag containing 2.5 per cent In. This slag is reduced electrothermieally to produce a bullion containing lead, tin, indium, and antimony. This bullion is treated electrolytically by a modification of the Betts process to yield a lead-tin alloy cathode and a high-indium (30 35%) anode slime. The anode slime is treated chemically to give a crude (99%) indium metal, which is refined eleetrolytically. The properties and uses of indium are discussed.

“…Indium possesses a high hydrogen overvoltage (1), near that of Hg and its standard potential is close to that of Cd. These two properties indicated that it might be useful as an energy producing anode and might show less tendency toward parasitic reactions which promote deterioration of commercial cells during storage.…”
