Изобретение относится к области получения материалов высокой чистоты, в частности к способу очистки галлия от различных примесей. Способ обеспечивает очистку от электроотрицательных металлов ( Zn, Al) путем растворения их в смеси соляной и азотной кислот необходимой концентрации при 40 - 50oС в условиях перемешивания. При адекватной глубине очистки в восемь раз снижается расход галлия.The invention relates to the field of obtaining materials of high purity, in particular to a method for purifying gallium from various impurities. The method provides purification from electronegative metals (Zn, Al) by dissolving them in a mixture of hydrochloric and nitric acids of the required concentration at 40-50 ° C under stirring conditions. With an adequate cleaning depth, gallium consumption is reduced eight times.
