Study of sintering behavior of PAN–PZT using dilatometry and co-relation with piezoelectric properties


Pb(Zr0.52Ti0.48)O3 (lead zirconate titanate, PZT) is one of the most widely used piezoelectric ceramic due to its superior piezoelectric performance. The ferroelectric and piezoelectric nature of PZT ceramics has led to numerous applications in electronic devices, such as actuators, sensors, capacitors, resonators and high-power transducers [1–5]. The sintering behavior of Pb(Al0.5Nb0.5)O3–Pb(Zr0.52Ti0.48)O3 (PAN–PZT) ceramics was investigated. The sintering process of PAN–PZT was divided into four stages based on the amount of in-situ linear shrinkage: (Stage 1) initial stage at sintering temperature RTrTsr to 770 1C, (Stage 2) perovskite formation stage at 770rTsr990 1C, (Stage 3) densification stage at 990rTsr1265 1C and (Stage 4) Pb-loss stage at Ts41265 1C.
