N2 - High-quality (1 - y)(Mg0.95Mn0.05)2(Ti0.95Sn0.05)O4y(Ca0.6La0.8/3)TiO3 ceramics were prepared by solid-state reaction. The products were characterized by scanning electron microscopy, X-ray diffraction, and network analyzer. (Mg0.95Mn0.05)2(Ti0.95Sn0.05)O4 has a dielectric constant (εr) of ∼14.21, a high quality factor (Qxf) of ∼347,000 GHz, and a temperature coefficient of resonant frequency (τf) of ∼-57.94 ppm/°C. To produce a temperature-stable material, (Ca0.6La0.8/3)TiO3, which has a large positive τf value of +212 ppm/°C, was added to 0.65(Mg0.95Mn0.05)2(Ti0.95Sn0.05)O40.35(Ca0.6La0.8/3)TiO3 has an excellent combination of microwave dielectric properties: εr ∼24.88, Qxf ∼133,000, and τf = 0 ppm/°C sinter at 1325°C, and can be utilized in the fabrication of microwave devices.
