Abstract
The effects of BiVO4 and CaTiO3 additives on the microwave dielectric properties of (Zn,Mg)TiO3 (ZMT) ceramics were investigated. BiVO4 as a sintering agent could effectively lower the firing temperature of ZMT ceramics below 930 °C. From XRD analysis, the secondary phase formation occurred when BiVO4 exceeding the solubility limit 2 wt% in ZMT matrix. SEM results indicated that due to the liquid phase sintering BiVO4 significantly improved the grain growth and densification. With an increase of BiVO4, the dielectric constant (εr) monotonously increased, but the quality factor (Qf) gradually decreased, and also the temperature coefficient of resonant frequency (τf) dramatically linear degraded. Besides, the addition of CaTiO3 can adjust the τf value of this system to a near zero level. (Zn0.65Mg0.35)TiO3 ceramic codoped with 1.5 wt% BiVO4 and 5 wt% CaTiO3 additives sintered at 930 °C exhibited the good microwave dielectric properties of εr = 23, Qf = 16177 GHz, τ f ≈ 1.0 ppm/°C.
