“…The degree of tetragonality (c/a) of B-0, B-CTAB and B-SDS are 1.0013, 1.0036 and 1.0051, respectively. These values are in good agreement with those of Liu and Ren [12] and Chandrakala et al [32]. The pronounced peak split in B-SDS powder was reflected in the high degree of tetragonality (c/a = 1.0051).…”

Lead-free Ba 0.85 Ca 0.15 Ti 0.9 Zr 0.1 O 3 (BCZT) ceramics had attracted much attention for the fabrication of microelectronic devices by virtue of their excellent dielectric, ferroelectric and piezoelectric properties. To understand the effects of both mean grain size and grain size distribution on the dielectric properties of lead-free Ba 0.85 Ca 0.15 Ti 0.9 Zr 0.1 O 3 (BCZT) ferroelectric relaxors, an original method was proposed. It is based on the surfactant-assisted solvothermal processing coupled with lowtemperature conventional sintering at 1250 °C. In this way, three highly dense BCZT with different mean grain size and dissimilar grain size distribution were designed. A significant increase of dielectric properties was obtained by a control of grain size and densification process. The dielectric constants measured were ranged from 5370 to 9646 and the dielectric loss was enhanced by 70%. Surprisingly, it was evidenced that there is unequivocal link between mean grain size with dielectric properties. Indeed, it was found that the presence of high density of refined grains leads to an improvement of dielectric 2 properties due to an enhancement of densification. This work may provide a new strategy to design ferroelectric materials with enhanced properties.

“…With the sintering temperature continuing to increase to 1450 °C, no heterogeneous phases were present and the (200) peak remained split into the (002) and (200) peaks in the 2 θ range of 44–46°, confirming a tetragonal phase structure. As a consequence, different sintering temperatures do not cause significant changes in the phase structure of porous BCZT piezoelectric ceramics [ 20 ]. The increasing intensity of the diffraction peaks and sharpness indicated the increasing crystallinity of the samples with increasing sintering temperatures.…”

Porous (Ba0.85Ca0.15)(Zr0.1Ti0.9)O3 (BCZT) piezoelectric ceramics with an oriented directional hole structure were prepared by using the tertbutyl alcohol (TBA)-based freeze-casting method. The influences of sintering temperatures on the microstructure and piezoelectric properties of porous BCZT ceramics were investigated both perpendicular and parallel to the freezing direction. With the increase in sintering temperatures and the porosities decreased from 58% to 42%, the compressive strength increased from 14.0 MPa to 25.0 MPa. In addition, the d33 value of 407 pC/N for the sample sintered at 1400 °C was obtained parallel to the freezing direction, which was 1.40 times that of the other direction.

The research of synthesized xBZT-BCT piezoelectric material have been carried out by using molten salt method. Piezoelectric material is a material that can generate electrical voltage when given voltage or mechanical strain. This material has the potential to be a good piezoelectric material. In this study, the method used is molten salt. Molten salt utilizes molten salt to speed up chemical reactions during the heating process.
