摘要：

The microwave dielectric properties of Nd(1-x)Ybx(Mg0.5Sn0.5)O-3 ceramics were examined with a view to exploiting them for mobile communication. The Nd(1-x)Ybx(Mg0.5Sn0.5)O-3 ceramics were prepared by the conventional solid-state method with various sintering temperatures. The X-ray diffraction, patterns of the Nd0.96Yb0.04(Mg0.5Sn0.5)O-3 ceramics revealed no significant variation of phase with sintering temperatures. An apparent density of 6.87 g/cm(3), a dielectric constant (epsilon(r)) of 19.48, a quality factor (Q x f) of 117,300 GHz, and a temperature coefficient of resonant frequency (tau(f)) of -61 ppm/degrees C were obtained for Nd0.96Yb0.04(Mg0.5Sn0.5)O-3 ceramics that were sintered at 1600 degrees C for 4 h.
