Abstract
Ferrous The paper presents the results of obtaining and studying the structure and properties of cobalt doped nickel-zinc ferrites with the general formula Ni0.3Zn0.7–xCoxFe2O4 (when x is 0, 0.2; 0.4; 0.6). Samples were obtained by solid-phase method in a tubular furnace with silicon carbide heaters at a temperature of 1150 °C. The morphology and chemical composition were studied on a JEOL JSM 7001F scanning elec-tron microscope with an Oxford Instruments energy dispersive analyzer (Inca X – max 80). The phase composition was studied using a Rigaku Ultima IV powder diffractometer. The data ob-tained suggest that all compositions from the prepared line of samples are monophasic and have a spinel structure. The effect of cobalt on the crystal lattice parameters of samples, which have a value from 8.3743 A to 8.4085 A, was also studied. A helium pycnometer – AccuPyc 1340 Micromeritics was used to study sample density. Com-paring the obtained data on the density of the samples on the pycnometer and the calculated X-ray density, the porosity of the material was calculated. It was found that as the degree of substitution of cobalt x increases from 0 to 0.6, an increase in the apparent density of the samples and a decrease in porosity are observed.
