摘要
The microwave dielectric properties of La2.98/3Ba0.01(Mg0.5Sn0.5)O-3 ceramics prepared by the conventional solid-state method were investigated for application in mobile communication. A 100 degrees C reduction of the sintering temperature was obtained by using CuO as a sintering aid. A dielectric constant of 20.0, a quality factor (Q x f) of 50,100 GHz and a temperature coefficient of resonant frequency tau(f) of -78.3 ppm/degrees C were obtained when La2.98/3Ba0.01(Mg0.5Sn0.5)O-3 ceramics with 0.25 wt.% CuO were sintered at 1500 degrees C for 4 h.
