Abstract
The influence of sintering temperature on the microwave dielectric properties and microstructure of the (1 − y)La(Mg0.4Sr0.1Sn0.5)O3–yCa0.8Sr0.2TiO3 ceramic system were investigated with a view to their application in microwave devices. The (1 − y)La(Mg0.4Sr0.1Sn0.5)O3–yCa0.8Sr0.2TiO3 ceramic systems were prepared using the conventional solid-state method. The X-ray diffraction patterns of the (1 − y)La(Mg0.4Sr0.1Sn0.5)O3–yCa0.8Sr0.2TiO3 ceramic system shifted to higher angle as y increased. A dielectric constant of 41.2, a quality factor (Q × f) of 56,900 GHz, and a temperature coefficient of resonant frequency of −6 ppm/ °C were obtained when the 0.4La(Mg0.4Sr0.1Sn0.5)O3–0.6Ca0.8Sr0.2TiO3 ceramic system was sintered at 1,550 °C for 4 h.
