Abstract
The influence of sintering temperature on the microwave dielectric properties and microstructure of the (1 − y)La0.97Sm0.03(Mg0.5Sn0.5)O3–yCa0.8Sm0.4/3TiO3 ceramic system were investigated with a view to their application in microwave devices. The (1 − y)La0.97Sm0.03(Mg0.5Sn0.5)O3–yCa0.8Sm0.4/3TiO3 ceramic systems were prepared using the conventional solid-state method. The X-ray diffraction (XRD) patterns of the (1 − y)La0.97Sm0.03(Mg0.5Sn0.5)O3–yCa0.8Sm0.4/3TiO3 ceramic system did not significantly vary with sintering temperature. The XRD patterns of the (1 − y)La0.97Sm0.03(Mg0.5Sn0.5)O3–yCa0.8Sm0.4/3TiO3 ceramic system shifted to higher angle as y increased. A dielectric constant of 37.5, a quality factor (Q × f) of 40,300 GHz, and a temperature coefficient of resonant frequency of 2.4 ppm/°C were obtained when the 0.425La0.97Sm0.03(Mg0.5Sn0.5)O3–0.575Ca0.8Sm0.4/3TiO3 ceramic system was sintered at 1,600 °C for 4 h.
