Improved Microwave Dielectric Properties of La(Mg0.5Sn0.5)O3 Ceramics with Yb3+ Doping
(Mg0.5Sn0.5)O3 ceramics were prepared by the conventional solid‐state method with various sintering temperatures. The X‐ray
diffraction patterns of the La0.97Yb0.03(Mg0.5Sn0.5)O3 ceramics revealed no significant variation of phase with sintering temperatures. An apparent density of 6.65 g/cm3, a dielectric
r) of 20.2, a quality factor (Q × f) of 56,800 GHz, and a temperature coefficient of resonant frequency (τ
) of −76.9 ppm/°C were obtained for La0.97Yb0.03(Mg0.5Sn0.5)O3
ceramics that were sintered at 1550°C for 4 h.
