In the XRD image, P(VDF-TrFE) nanofiber only showed one peak at 2θ = 19.5°, which indicated the formation Conclusions In this work, we proposed a high-performance, flexible and environmental-friendly piezoelectric nanogenerator prepared from BZT-BCT/P(VDF-TrFE) nanofibers. Both BZT-BCT...
Figure 1b and c shows the scanning electron microscope (SEM) image and X-ray diffraction (XRD) spectrum of BZT-BCT NWs, indicating that the diameter and length of the NWs are 100–150 nm and 1–2 μm, respectively, and the XRD spectrum of the NWs corresponds with that shown in ...
采用大气等离子喷涂制备了Ta_2O_5原位复合钽基纳米晶涂层,利用SEM,微束XRD,微动摩擦磨损实验机及非接触三维表面轮廓仪等技术手段并结合计算分析,考察了喷涂功率,主气(... 李晓倩,王富国,梁爱民 - 《金属学报》 被引量: 0发表: 2021年 水热合成铌酸盐粉体及掺杂改性压电陶瓷性能的研究 压电、铁电陶瓷材料广泛...
XRD studies revealed the presence of both ceramic and polymer phases in the (BZT-BCT)-epoxy composites. SEM studies showed a uniform distribution of ceramic particles in the epoxy matrix, which confirmed the 0-3 connectivity in the composites. Dielectric studies revealed an increase in relative ...
XRDDielectric responseLead free 0.5[Ba(Zr_(0.2)Ti_(0.8))O_3]-0.5[(Ba_(0 7)Ca_(0 3))TiO_3]/[BZT-BCT 50/50] ceramics were synthesized by High Energy Ball Milling(HEBM) process. The effect of microwave sintering was observed at 1200°C. Density measurement show the effect of ...
XRD results showed the evidence of the phase transitions and morphotropic phase boundary (MPB) regions of BCT–BZT and BCZT ceramics. The phase transitions in the triple point showed a sensitive variation of electric properties around MPB regions. The excellent electric properties ( ε r =~9000,...
Tetragonal and rhombohedral phase coexistence is observed at room temperature from X-ray diffraction (XRD) spectra. Rhombohedral phase is identified between the 83 K and 273 K from temperature dependent Raman studies. Raman results are in excellent agreement with those obtained from temperature ...
X-ray diffraction (XRD) study revealed the single perovskite phase at room temperature (RT) for all the MPB compositions. Scanning electron microscopy (SEM) study of the sintered (BZT–BCT) ceramics revealed dense and homogeneous packing of grains. A morphotropic phase boundary (MPB), consisting...
