Structure, piezoelectric, dielectric and ferroelectric properties of lead-free (1-x)(Ba0.85Ca0.15)(Ti0.93Zr0.07)O3-x(Bi0.5K0.5)TiO3 ceramics

Influence of K 0.5 Bi 0.5 TiO 3 on the structure, dielectric and ferroelectric properties of (Ba,Ca)(Zr,Ti)O 3 ceramics

“…Regarding the use of perovskite compounds for this purpose, it was reported that the sintering temperature of BT ceramics modified with KBT can be decreased to 1280ºC for 10 mol% KBT [20] and to 1125ºC for 65 mol% KBT [24]. In another study, it was found the use of 4 mol% KBT enabled the sintering temperature of (Ba0.85Ca0.15)(Ti0.93Zr0.07)O3 to be reduced from 1500ºC to 1280ºC [19]. Similarly, several reports have shown that other Bi-based perovskite compounds can effectively enhance the densification of BT-based ceramics.…”

AC conductivity and phase transition of the BST–BFO ceramic doped with Yb

“…the transition from the antiferroelectric to the paraelectric state) at high temperatures is most likely due to space charge polarization. [36][37][38][39]…”

Local Structural Investigation of (Ba,Ca)(Zr,Ti)O3 and Ca(Zr,Ti)O3 by X‐Ray Fluorescence Holography

“…(Ba,Ca)(Zr,Ti) O 3 (BCZT) was developed by adding fourth and fifth elements into a typical ferroelectric BaTiO 3 , and it is expected to be an alternative material to PZT because it shows high piezoelectricity and contains no toxic elements. [5][6][7][8] It is important to investigate the local structures of this material in order to determine the origin of its excellent piezoelectric property. The investigation of the local structures of dilute elements, especially around the dopant elements, is one of the interesting areas to understand the excellent piezoelectric properties of BCZT.…”
