“…This is caused by the structure transforming from orthorhombic to rhombohedral [4,6]. It is concluded that the increased zirconium content changes the structure of BZT ceramic from tetragonal to rhombohedral, which is confirmed by the gradual merging of XRD peaks [6,8,21]. Finally, the dense ceramic discs exhibit large grains and a small proportion of fine grains with pores.…”

“…The relative density of all samples is 93.5% ± 0.21%. The addition of zirconium does not affect density [8]. A sintering temperature of 1300 • C is sufficient to fuse the as-calcined Ba(Zr x Ti 1−x )O 3 powders, and a calcination temperature of 1100 • C has an insignificant effect on the bulk density.…”

“…The position of each dielectric peak moves to a higher temperature with the addition of Zr, which ranges from 0 to 3 mol.%. For x = 0.08, the dielectric peak is broad because of the inhomogeneous distribution of Zr 4+ ions in the Ti sites and the non-uniform stress in the grains [8,23]. The highest dielectric constant is 19,600 for Ba(Zr 0.03 Ti 0.97 )O 3 .…”

“…Doping BaTiO 3 with ZrO 2 can improve the dielectric and piezoelectric properties because the chemical stability of Zr 4+ is greater than that of Ti 4+ [4][5][6][7]. In addition, the Curie temperature also changes; that is, it decreases as the Zr content increases [5][6][7][8].…”

In this study, we investigated the effect of zirconium content on lead-free barium zirconate titanate (BZT) (Ba(ZrxTi1−x)O3, with x = 0.00, 0.01, 0.03, 0.05, and 0.08), which was prepared by the sol–gel method. A single-phase perovskite BZT was obtained under calcination and sintering conditions at 1100 °C and 1300 °C. Ferroelectric measurements revealed that the Curie temperature of BaTiO3 was 399 K, and the transition temperature decreased with increasing zirconium content. At the Curie temperature, Ba(Zr0.03Ti0.97)O3 with a dielectric constant of 19,600 showed the best performance in converting supplied mechanical vibration into electrical power. The experiments focused on piezoelectric activity at a low vibrating frequency, and the output power that dissipated from the BZT system at 15 Hz was 2.47 nW (30 MΩ). The prepared lead-free sol–gel BZT is promising for energy-harvesting applications considering that the normal frequencies of ambient vibration sources are less than 100 Hz.

“…Zr 4 þ has been chosen to form Ba(Zr x Ti 1 À x ) O 3 (BZT) ceramics. Furthermore, the electron hopping between Ti 4 þ and Ti 3 þ can also be depressed by the substitution of Ti with Zr [12][13][14][15][16].…”
