Abstract
The results of high-temperature electrochemical synthesis are presented for intermetallic nickel and holmium powders. The optimal conditions for the synthesis of these compounds were found, including: temperature of the electrolytic process (923–1073 K), cathode current density (0,5–1,9 A/cm2) and the electrolytic bath concentration ratio, mol.%: KCl(48,25÷49,5)–NaCl(48,25÷49,5)– HoCl3(0,5÷3,0)–NiCl2(0,5÷2,5). The resulting powder composition was studied by the X-ray diffraction analysis and scanning electron microscopy methods.
