Abstract
NiCuZn ferrites with different contents of CaO–B2O3–SiO2 glasses were synthesized by a conventional ceramic technology and sintered at 1050°C. It was found that the addition of CaO–B2O3–SiO2 influenced the magnetic and dielectric properties of the ferrites. The saturation magnetization increased at first and reached its maximum with the sample of 2wt% CaO–B2O3–SiO2, and then decreased. The initial permeability decreased with the content of CaO–B2O3–SiO2 but the cut-off frequency increased. The quality factor decreased first and then increased; the maximum quality factor was obtained in the sample with 3wt% CaO–B2O3–SiO2. With increasing content of CaO–B2O3–SiO2, the permittivity increased sharply. The possible reasons responsible for these changes are explained.
