Abstract:
In this work are presented the results of high-temperature electrochemical synthesis of intermetallic compounds of holmium and of metals of the iron group powders. The principal possibility of synthesis of holmium and nickel (cobalt, iron) intermetallic compounds electrochemically from chloride melt is showed.
Objective: Development of the electrochemical method of producing nanopowders of intermetallic compounds of holmium and Nickel (Cobalt, Iron) in halide melts.
High-temperature electrochemical synthesis of intermetallides of holmium and Nickel was carried out in a galvanostatic mode in the melt KCl-NaCl-HoCl3-NiCl2.
Identification and study of the obtained samples were carried out by the following methods:
• X-ray elemental analysis elemental analyzer SPECTROSCAN MACS-GV (Spa «device»);
• X-ray method– x-ray diffractometer DRON-6 (SPE «Burevestnik»), x-ray diffractometer D2 Phazer;
• Diffraction analysis – laser diffraction analyzer FritschAnalysette-22 (Nanotech);
• Scanning electron microscopy – scanning electron microscope VEGA3 LMH(TESCAN) with energodispersive x-ray microanalyzer (OXFORD).
Our investigation showed the main potentiality of holmium and nickel (cobalt, iron) intermetallic compounds synthesis by electrolysis of halide melts;
The X-Ray phase analysis and laser diffraction particle size analysis of the synthesized powders showed the presence of different stable phases of the alloys with cobalt and holmium: IiÑi5, IiÑi3, Ii2Ñi17 ;Ohe results of X-ray phase analysis indicated the presence of intermetallic compounds stable phases of holmium with iron: HoFe2 and HoFe5.Ii2Ñi17 .
