Abstract
(Mg0.97Zn0.03)2(Ti0.95Sn0.05)O4 ceramics by adding CaTiO3 have been prepared via the solid-state reaction method. The microstructures of samples are systematically studied in order to establish the effects of sintering temperature and additives on microwave dielectric properties of (Mg0.97Zn0.03)2(Ti0.95Sn0.05)O4 ceramics by X-ray diffraction and scanning electron microscopy. A fine combination of microwave dielectric properties (εr = 14.57, Q × f = 183,468 GHz, τf = −43.7 ppm/°C) was achieved for (Mg0.97Zn0.03)2(Ti0.95Sn0.05)O4 ceramics sintered at 1,390 °C for 4 h. CaTiO3, as a τf compensator, was added to form a temperature-stable ceramic system. For (1−x) (Mg0.97Zn0.03)2(Ti0.95Sn0.05)O4−xCaTiO3 system, 0.93(Mg0.97Zn0.03)2(Ti0.95Sn0.05)O4−0.07CaTiO3 ceramic sintered at 1,390 °C had optimal dielectric properties (εr = 18.32, Q × f = 94,715 GHz, τf = −4.1 ppm/°C) which satisfied microwave applications in resonators, filters and antenna substrates.
