2020年3月15日 · In this paper, the effect of BaTiO 3 on dielectric, ferroelectric, and piezoelectric properties was observed in (1-x)[Bi 0.5 (Na 0.4 K 0.1)TiO 3] – xBaTiO 3 ceramics (BNKT-BT, with x = 0; 0.01; 0.02; 0.03 and 0.04). The phase formation and microstructure of BNKT-BT ceramics were examined by X-ray diffraction (XRD), the Raman scattering ...

2018年9月1日 · The phase formation and microstructure of BNKT-BT ceramics were examined by X-ray diffraction (XRD), the Raman scattering spectra, and scanning electron microscopy (SEM).

2022年1月15日 · This research explored the influence of Nb 5+ doping on the electrical properties and microstructure of [0.852(Bi 0.5 Na 0.5)-0.11(Bi 0.5 K 0.5)-0.038Ba]Ti (1-x) Nb x O 3 (designated as BNKT-BT). The BNKT-BT samples were fabricated and the XRD results showed that the doping of Nb 5+ ions induced a transformation from the coexistence of both ...

BiAlO3-modified BNKT lead-free ceramics have been studied and achieved the optimal energy storage density, which are as follows: 0.754 J/cm3, 0.73 J/ cm3, and 1.15 J/cm3, respectively [17–19]. Unfortu-nately, the mechanisms related to the formation of a small remnant polarization and large permittivity have not been unified.

Lead-free Bi 0.5 (Na 0.78 K 0.22 ) 0.5 TiO 3 (BNKT) piezoelectric ceramics were synthesized by the solegel technique. The effects of sintering temperatures on the crystal structure, microstructure, densification, dielectric, ferroelectric and electric field-induced strain behaviors of the BNKT ceramics were investigated.

2015年5月31日 · Temperature dependent dielectric and the polarization vs. electric field (P–E) studies confirmed the coexistence of ferroelectric (FE) and anti-ferroelectric (AFE) phases in the BNT–BT and...
