The electrodeposition process of Sc at liquid Zn from the chloride-fluoride fused mixtures under the pulse-step-like conditions is investigated to prepare an alloy with maximum content of Sc. The electrolysis is carried out at 780-800°C in electrolyte of KCl + NaCl - 6% NaF - 18 mass.% ScF3. It is shown that the combined use of step-like regulation of current and its pulsed local affecting at the surface of liquid electrode with additional stirring can result in preparation of Zn-Sc alloys with the Sc content of 4-5 % and current efficiency up to 60%.
