X-ray diffraction (XRD) analysis revealed that the FN complexes were completely dissolved in BNKT perovskite and the structural transition occurred from ferroelectric to relaxor...

2024年9月1日 · In summary, BNKT-xST ceramics were synthesized by solid-phase method. The XRD findings indicated ST doping induce a phase transition from the rhombohedral to the tetragonal. Dielectric profiles and P-E hysteresis loops show that ST doping induces strong relaxor properties and enhanced ergodic properties.

2018年5月5日 · The BNKT-Na0.85 ceramic exhibited a giant field-induced strain of 0.45% at 5 kV/mm (900 pm V −1). In-situ X-ray diffraction (XRD) and electrical properties examinations were used to identify the main origin of the giant strain and ascertain the evolution of the crystal structure under electric fields.

2020年2月1日 · The XRD patterns confirmed that Ta 5+ ions had completely dissolved into the lattice of BNKT-BST-100 x Ta ceramics. Meanwhile, the temperature of R 3 c -PNRs (T s) was found to shift towards room temperature in dielectric …

We studied the effect of Bi4Ti3O12 (BiT) platelet addition in Bi0.5 (Na0.75K0.25)0.5TiO3 (BNKT) ceramics by preparing two kinds of BNKT ceramics. One type of BNKT ceramic was fabricated by a...

In this study, lead-free (1−x) [Bi0.5 (Na0.8K0.2)0.5TiO3]–x [Ba0.844Ca0.156 (Zr0.096Ti0.904)O3] (BNKT–BCZT, where x = 0.0, 0.025, 0.05, 0.075, and 0.1) ceramics were produced by tape-casting...

2014年1月3日 · Lead-free BNKTx piezoceramics with x ranging between 0.18 and 0.24 have been synthesized using a conventional solid state reaction ceramic method. It has been established that all compositions exhibit pure perovskite ferroelectric phase.

In this work, Bi(Mg2/3Nb1/3)O3 (BMN) was introduced to improve the electrical properties and energy storage performance of Bi0.5(Na0.82K0.18)0.5TiO3 (BNKT) ceramics, and the lead-free ceramics BNKT-xBMN (x = 0.02, 0.04, 0.06, 0.08, 0.10, 0.12, 0.14, 0.16) were synthesized via a traditional sintering process.

2025年1月23日 · Macroscopic properties, including temperature-dependent dielectric measurements, X-ray diffraction (XRD), scanning electron microscopy (SEM), and ferroelectric measurements, are in good accordance with the phenomenon observed at the atomic scale.

(BNKT) particles were synthesized by using sol-gel method. The samples were investigated by X-ray diffractometry (XRD), scanning electron microscope (SEM), energy-dispersive X-ray spectroscopy (EDX), and vibrating sample magnetometer (VSM). The absorption of microwaves of the lead-free BNKT powders is determined
