摘要：
The microwave dielectric properties of Nd(1-2x/3)Srx(Mg0.5Sn0.5)O-3 ceramics were examined with a view to their exploitation in mobile communication. The Nd(1-2x/3)Srx(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 Nd2.94/3Sr0.03(Mg0.5Sn0.5)O-3 ceramics revealed no significant variation of phase with sintering temperatures. A density of 6.88 g/cm(3), a dielectric constant (epsilon(r)) of 19.3, a quality factor (Q x f) of 91,200 GHz, and a temperature coefficient of resonant frequency (cf) of -65ppm/degrees C were obtained for Nd2.94/3Sr0.03(Mg0.5Sn0.5)O-3 ceramics that were sintered at 1550 degrees C for 4 h.
