Abstract
This study elucidates the microwave dielectric properties and microstructures of Nd(Mg0.5−xNixSn0.5)O3 ceramics with a view to their potential for microwave devices. The Nd(Mg0.5−xNixSn0.5)O3 ceramics were prepared by the conventional solid-state method with various sintering temperatures. The X-ray diffraction patterns of the Nd(Mg0.43Ni0.07Sn0.5)O3 ceramics revealed no significant variation of phase with sintering temperatures. A dielectric constant (\( \varepsilon_{r} \)) of 19.3 and a quality factor (Q × f) of 93,400 GHz and a temperature coefficient of resonant frequency (\( \tau_{f} \)) of −66 ppm/ °C were obtained for Nd(Mg0.43Ni0.07Sn0.5)O3 ceramics that were sintered at 1,550 °C for 4 h.
