摘要：

A process of electrochemical synthesis of nanodimensional powders of neodymium (praseodymium) hexaborides and Pr(Nd) (x) -Fe(Ni, Co) (y) -B (z) ternary compounds from chloride-fluoride melts is developed. The composition of the fabricated powders is investigated by X-ray phase analysis, and particle sizes are determined using laser diffraction analysis. The dependence of the phase composition of the powders on the temperature, component ratio, current density, and electrolysis potential is established. Optimal conditions of the fabrication process of nanodimensional powders of neodymium and praseodymium borides and Nd11Fe4B4 ternary compound are found.
