Abstract: In this work, preparation of powders of multicomponent (NiFeCoCuZn)xOy nanoparticles by the method of combined electrical explosion of wires in an atmosphere of Ar + 25 mol % O2 gases is demonstrated. Heating of wires with a current pulse with a density of 3,15×107 A/cm2 at a buffer gas pressure of 0,15 MPa leads to the formation of nanoparticles of multicomponent oxide with an average size of about 54 nm. The particle size distribution is described by the normal-logarithmic law. The particles have the spherical shape. The synthesized sample contains two crystalline structures corresponding to rock salt (Fm3m, a = 4,213 Å) and spinel (Fd3m, a = 8,389 Å). The results of the study show that the crystal structure of (NiFeCoCuZn)xOy nanoparticles can be optimized by both changing the ratio of divalent and trivalent metals in the wire explosion products and changing the thermodynamic conditions for the formation of nanoparticles.
