Abstract

High-quality (1 - x)(Mg_0.9sCo_0.05)2(Ti_0.9sSn_0.05)O₄-x(Ca_0.8Sm_0.4/3)TiO₃ ceramics were prepared by solid-state reaction. The products were characterized by scanning electron microscopy, X-ray diffraction, and network analyzer. (Mg_0.95Co_0.05)2(Ti_0.95Sn_0.05)O₄ (MCTS) has a dielectric constant (ε_r)of ∼14.7, a high quality factor (Qxf)of ∼330,134GHz, and a temperature coefficient of resonant frequency (τ_f)of ∼-46ppm/°C. To produce a temperature-stable material, (Ca_0.8Sm_0.4/3)TiO₃ (CST) which has a large positive value τ_f of +400ppm/°C, was added to MCTS. 0.84 MCTS-0.16CSTs an excellent combination of microwave dielectric properties: ε_r ∼ 22.5, Qxf ∼ 206,000 GHz (at 9 GHz), and τ_f ∼ -0 ppm/°C sinter at 1325°C, and can be utilized in the fabrication of microwave devices.
