摘要
FIELD: chemistry.SUBSTANCE: invention relates to electrochemical production of holmium and nickel intermetallic compounds nanopowders, which can be used as catalysts in chemical and petrochemical industries, hydrogen energy for reversible sorption of hydrogen, as well as for magnetic material creation. Electrolysis of a molten mixture containing potassium chloride, sodium chloride, holmium (III) chloride and nickel (II) chloride is performed in a quartz cell on a tungsten electrode at a temperature of 973°K and a current density of 0.5÷1.9 A/cm.EFFECT: decreased temperature of electrolysis and obtaining of nickel and holmium intermetallic compounds nanopowders.6 dwg, 3 tbl, 5 ex
