Dielectric and ferroelectric properties of 0.8PZT–0.2PCN ceramics under sintering conditions variation

Synthesis and Dielectric Properties of 0.9Pb(Zr1/2Ti1/2)O3– 0.1Pb(Fe1/3Nb2/3)O3Ceramics

“…1PFN has been affected on the phase formation of PZT ceramic. This trend is similar to those reported in the literature [6,7,12,13].…”

Effect of dwell time during sintering on piezoelectric properties of (Ba0.85Ca0.15)(Ti0.90Zr0.10)O3 lead-free ceramics

“…The average grain size and the density of these ceramics increase with increasing the dwell time due to the grain growth controlled by the boundary diffusion, confirming that the different dwell time can enhance the diffusion mechanism and promote the densification of these ceramics. This result is in agreement with reported results [18][19][20][21]. Therefore, the increase in ε r value can be attributed to the larger grain size of BCTZ ceramics.…”

“…The peak position of BCTZ ceramics is shifted to a lower angle with increasing the dwell time of 1-4 h due to the lattice distortion, and then is shifted to a higher angle with further increasing the dwell time of 5-6 h. Moreover, different peak shapes are also demonstrated for the BCTZ ceramic sintered at a dwell time of 6 h. The sintering condition (too long dwell time) affects the crystal structure of BCTZ ceramics in this work. Similar phenomenon has been observed for the lead-based ceramics [18]. Fig.…”

“…4(b) plots the 2P r and 2E c values of BCTZ ceramics as a function of dwell time. The 2P r value slightly increases with increasing the dwell time, while the 2E c value decreases [18]. Fig.…”

“…Surprisingly high d 33 values of ∼350-460 pC/N have been reported for the BaTiO 3 ceramics prepared by different sintering techniques [16,17]. In the past, different sintering conditions strongly affect the electrical properties of piezoelectric ceramics [18][19][20][21]. Nevertheless the relationship between microstructure and electrical properties is still lacking for Ca and Zr-modified BaTiO 3 ceramics, where its microstructure is modified by changing the sintering condition (i.e., dwell time during sintering) in this work.…”
