Abstract

(Pb1-x,Cax)(Zr1-y,Tiy) O3 (PCZT) perovskite type ceramics exhibit microwave dielectric properties of high dielectric constant (εr), high unloaded Q and small temperature coefficient of resonant frequency (τf). However, the sintering temperature was as high as 1450°C and the microstructure and dielectric properties were difficult to control due to high PbO volatility. In this paper, we report the effect of PbO loss on microstructure and microwave dielectric properties of PCZT ceramics. Suppression of PbO loss by B-site ion substitution in PCZT was also investigated.
