Abstract
The influence of Ca0.8Sr0.2TiO3 on the microstructures and microwave dielectric properties of 1 wt% Li2WO4-doped Zn2SnO4 ceramics were investigated by the conventional solid-state method. The dielectric constant increased from 6.2 to 6.9, the quality factor (Q × f) decreased from 9200 to 7500 GHz, and the temperature coefficient of resonant frequency (τ f ) increased from −22 to +18 ppm/°C as y increased from 0.25 to 0.35 when 1 wt% Li2WO4-doped (1 − y)Zn2SnO4–yCa0.8Sr0.2TiO3 ceramic system sintered at 950 °C for 4 h. A 1 wt% Li2WO4-doped 0.7Zn2SnO4–0.3Ca0.8Sr0.2TiO3 ceramic system that was sintered at 950 °C for 4 h had a dielectric constant of 6.6, a quality factor (Q × f) of 8600 GHz, and a temperature coefficient of resonant frequency of 1.0 ppm/°C.
