Cl. Huang et Mh. Weng, The effect of PbO loss on microwave dielectric properties of (Pb,Ca)(Zr,Ti)O-3 ceramics, MATER RES B, 36(3-4), 2001, pp. 683-691
(Pb1-x,Ca-x)(Zr1-y,Ti-y)O-3 (PCZT) perovskite type ceramics exhibit microwa
ve dielectric properties of high dielectric constant (epsilon (r)), high un
loaded Q and small temperature coefficient of resonant frequency (tau (f)).
However, the sintering temperature was as high as 1450 degreesC and the mi
crostructure and dielectric properties were difficult to control due to hig
h PbO volatility. In this paper, we report the effect of PbO loss on micros
tructure and microwave dielectric properties of PCZT ceramics. Suppression
of PbO loss by B-site ion substitution in PCZT was also investigated. (C) 2
