The recent far‐spread interest in powder metallurgy has suggested the production of relatively pure metal powders or metal‐alloy powders by the fused electrolyte method. The three major metal products of the fused electrolyte industry are sodium, aluminum, and magnesium. In each case the temperature of the fused salt bath is decidedly above the melting point of the metal produced. Accordingly all three metals are removed from the cells in liquid form. But when the melting point of the metal is above the bath temperature the metal will be deposited as small crystals or as dendrites. About 20 metals have, according to the literature, been deposited in this form. The advantage of operating at lower bath temperatures and of getting a solid rather than a liquid product is offset by the difficulty in eliminating the entrained or adherent fused salt from the metal crystals. Methods for removing adherent bath salts from the metal crystals are discussed. Numerous examples are cited to illustrate the fundamental reactions taking place at the cathode and at the anode when solid metals or alloys are being deposited from a fused salt bath. At less than 4 amp./dm.2 a smooth metal plate is possible, whereas above this current density the dendrites appear.
