<p>The aim of this work was to create and study of ferrite nickel-cobalt powders, using sol-gel technology withparticipation of auto-combustion. After completing the process autocombustion was obtained only one phase,which corresponded to the cubic structure of spinel space group Fd3m. It was found that the average size ofcoherent scattering regions not exceeding 62 nm. The dependences of the lattice parameter, X-ray density andspecific surface area of the ferrite powders from nickel content were found. It was shown that at substitution ofcations cobalt on cations nickel latest give preference only B positions, thus displacing part of Fe³⁺ in the Apositions.</p><p><strong>Keywords: </strong>sol-gel technology, nickel-cobalt ferrite, nanosized powder, lattice parameter, cationicdistribution.</p>
