Abstract: Ba₃Zn_ZCo_2-ZFe₂₄O₄₁/SiO₂(Zvaries from 0.0 to 1.2 in step of 0.4) microcrystalline glass ceramics were prepared by citrate sol-gel process at 1 200℃in the system of BaO-Fe₂O₃-CoO-ZnO-SiO₂. The samples were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The complex dielectric constant and complex permeability of Ba₃Zn_ZCo_2-ZFe₂₄O₄₁/SiO₂ microcrystalline glass ceramics were measured in the range of 0.1 6.0 GHz by transmission/reflection coaxial line method. The natural resonance phenomenon was observed inμ″spectra for all the Ba₃Zn_ZCo_2-ZFe₂₄O₄₁/SiO₂ microcrystalline glass ceramics, which was closely affected by the substitution of Zn²⁺ ion.
