发明名称 СПОСОБ ЭЛЕКТРОХИМИЧЕСКОГО РАФИНИРОВАНИЯ ГАЛЛИЯ
摘要 FIELD: methods of electrochemical refining of gallium. ^ SUBSTANCE: proposed method includes conversion of crude gallium into electrolyte by anode dissolving in sodium hydroxide solution, reduction of ionized gallium on cathode in electrolyzer with porous electric conducting diaphragm at size of pores from 50 mcm to 500 mcm; voltage to it is supplied from independent source. Current intensity on diaphragm is equal to 0.1-0.4 of current intensity on electrolyzer. ^ EFFECT: increased degree of cleaning gallium from electric positive admixtures. ^ 1 tbl, 1 ex
