摘要

High-quality (1 - x)(Mg0.9sCo0.05)2(Ti0.9sSn0.05)O4-x(Ca0.8Sm0.4/3)TiO3 ceramics were prepared by solid-state reaction. The products were characterized by scanning electron microscopy, X-ray diffraction, and network analyzer. (Mg0.95Co0.05)2(Ti0.95Sn0.05)O4 (MCTS) has a dielectric constant (εr)of ∼14.7, a high quality factor (Qxf)of ∼330,134GHz, and a temperature coefficient of resonant frequency (τf)of ∼-46ppm/°C. To produce a temperature-stable material, (Ca0.8Sm0.4/3)TiO3 (CST) which has a large positive value τf of +400ppm/°C, was added to MCTS. 0.84 MCTS-0.16CSTs an excellent combination of microwave dielectric properties: εr ∼ 22.5, Qxf ∼ 206,000 GHz (at 9 GHz), and τf ∼ -0 ppm/°C sinter at 1325°C, and can be utilized in the fabrication of microwave devices.
