The Ni-Co ferrites were prepared by the technology sol-gel with participation of auto-combustion and sintered at temperature 1573 K in air. The effects of Ni2+ ions addition on the microstructure and electric properties of NixCo1 – xFe2O4 ferrites were systematically studied. The added of Ni2+ ions significantly affects the formation of pores and grain size of ferrites. By doping with nickel ions the pores decreased and a dense material are obtained. The micro-hardness values increases from 5,16 GPa to 8,59 GPa with increasing nickel contents. The Hall coefficient, conductivity type, concentration of charge carriers and specific conductivity were found. In Ni-Co ferrites Hall mobility is within the limits from 7.04·10 – 1 cm2/V·s to 4.38 cm2/V·s. |
