2024年2月1日 · In this study, a BCZT silver loaded piezoelectric antibacterial coating (marked as BCZT-Ag) was prepared by photochemical reaction combined with hydrothermal synthesis. The composition and morphology of the coating were studied. The effects of silver loaded and polarization on the release properties of silver ions in coating were analyzed.

2021年7月15日 · In this paper, we report the synthesis of vanadium (V)-doped Ba 0.9 Ca 0.1 Ti 0.9−x V x Zr 0.1 O 3 (BCZT) ceramic oxides prepared using conventional solid-state reaction methods. The X-ray diffraction (XRD) pattern confirmed the formation of the tetragonal phase—with the space group P 4 mm—in all samples.

2023年3月1日 · Fig. 1 (a) shows an X-ray photoelectron spectroscopy (XPS) spectrum of Co 2p and Ba 3d for the BCZT - 0.02Co material. In the range of 775–800.5 eV, the peaks of Co 2p 3/2 and Ba 3d 5/2 and the peaks of Co 2p 1/2 and Ba 3d 3/2 overlap at approximately 777.8 eV and 793.3 eV, respectively [33].

2020年11月23日 · The results of XRD, FTIR, SEM and TEM indicated that BCZT powders could be obtained in even 60 min at a low synthesis temperature of 180 °C, which were well-crystallized with stoichiometric ...

Ba0.85Ca0.15Zr0.1Ti0.9O3 (BCZT) ceramics with excellent piezoelectric properties and environment friendliness are very potential alternatives for PbZrxTi1−xO3 (PZT) ceramics.

在这里，我们深入研究了 X 射线衍射 (XRD)、拉曼散射、介电性能、局部压电响应和光致发光 (PL) 的温度依赖性，以研究通过以下方式合成的 BCZT 陶瓷中的相变序列化学路线。

2023年10月3日 · BCZT is a new ceramic system based on BaTiO 3 ceramic system in which Ca 2+ and Zr 4+ are co-doped. Its superior electrical properties are comparable to several mainstream lead-based piezoelectric ceramics, and can be regarded as a strong competitor of lead-based piezoelectric ceramics [3].

Benefiting from the grain coarsening and the restriction of the oxygen vacancy, the BCZTC x S y ceramics exhibited improved ferroelectric and piezoelectric performance. This study can provide an experimental basis for further modification of BCZT ceramics.

2020年5月11日 · Based on the previous SEM, EDS, XPS and impedance spectroscopy, BCZT-O 2 ceramics have the best densification, larger grain size, the lowest oxygen vacancy concentration and O-T phase boundary near room temperature, which causes its …

The microstructure and electrical properties of BCZT-xCr samples were systematically studied. XRD and Raman results showed that all samples possessed a single phased perovskite structure and were...
