Abstract
The microwave dielectric properties of La(Mg0.5-xSrxSn0.5)O3 ceramics were examined with a view to their exploitation for wireless communications. The La(Mg0.5-xSrxSn0.5)O3 ceramics were prepared by the conventional solid-state method with various sintering temperatures. The La(Mg0.5-xSrxSn0.5)O3 ceramics contained La2O3. An apparent density of 6.56 g/cm3, a dielectric constant (ϵr) of 20.5, a quality factor (Q × f) of 107,900 GHz, and a temperature coefficient of resonant frequency (τf) of -84 ppm/°C were obtained for La(Mg0.4Sr0.1Sn0.5)O3 ceramics that were sintered at 1500 °C for 4 h.
