摘要：

NiCuZn ferrites with different contents of CaO-B2O3-SiO2 glasses were synthesized by a conventional ceramic technology and sintered at 1050 degrees 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 2 wt% 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 3 wt% CaO-B2O3-SiO2. With increasing content of CaO-B2O3-SiO2, the permittivity increased sharply. The possible reasons responsible for these changes are explained. (C) 2011 Elsevier B.V. All rights reserved.
