Abstract—The mechanism of electrode processes for preparing a refined lead–tin alloy via electrolysis is presented. Rather close potentials of lead and tin allow the metals to deposit and precipitate from solutions of simple salts without forming new compounds and solid solutions. A lead–tin alloy is deposited on the cathode when passing electric current through the following solution (g/L): 94 SnSiF6, 65 PbSiF6, and 86 H2SiF6. Such metals as Zn, Cd, Fe, Ni, and Sn precipitate to the solution. Impurities of As, Sb, Bi, Cu, and Ag precipitate to a slime. The content of each metal in the solution does not exceed 0.004%. The process is carried out at a current efficiency of 95% and an electric energy consumption of 174 kW h t–1. The purity of the electrolyte alloy is 99.992%.
期刊介绍：
Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
