| Abstract: | The microwave dielectric materials of CaTiO3-Ca(Zn1/3Nb2/3)O3-CaSmAlO4 ceramics were prepared by conventional solid state reaction method. The effects of modification in the proportion of composition on the sintering behavior and the microwave dielectric properties of CaTiO3-Ca(Zn1/3Nb2/3)O3-CaSmAlO4 ceramics were studied. The crystalline phase and microstructure of the sintered samples were characterized by XRD and SEM respectively. Most of these CaTiO3-Ca(Zn1/3Nb2/3)O3-CaSmAlO4 ceramics exhibit excellent microwave dielectric properties: εr=45～50, Q·f0≥3 8000 GHz, τf<10×10–6℃–1. |
