“…In terms of tan δ, various factors, for instances, chemical composition, microstructure, temperature, frequency, etc. have an influence on tan δ [26]. This work found that the 50BZT-50BCT ceramic showed the largest tan δ in low frequency range, as seen in Figure 5(b), implying that the movement of domain wall strongly occurred in this composition [26].…”

The concept of composition-induced phase transformation in Lead Zirconate Titanate (PZT) at the Morphotropic Phase Boundary (MPB) has been employed to improve functional properties of the (1-x)BZT-(x)BCT ceramic. However, it was observed that the phase diagram of the (1-x)BZT-(x)BCT ceramic is different to the PZT. As a result, the nature of the superior functional properties found in (1-x)BZT-(x)BCT ceramic is unlike PZT and still unclear so far. In this work, functional properties; dielectric, ferroelectric, energy storage, and piezoelectric properties, of the (1-x)BZT-(x)BCT ceramics where x = 0.3 mol% to 0.6 mol% were evaluated at room temperature in comparison to the identification of phase coexistence using synchrotron x-ray powder diffraction (SXPD). This work found that changes of BCT content had a strong impact on the observed coexisting phases and functional properties. Moreover, the composition that showed the highest piezoelectric properties did not present the largest of saturation polarization. This implies that the functional properties of the (1-x)BZT-(x)BCT ceramics are not dependent on the presence of polarizations under the application of electric field. The contribution of non-180° domain switching also plays a vital role, especially in the piezoelectric properties. These findings would help to extend our knowledge of the nature of the (1-x)BZT-(x)BCT ceramic.

“…Since the discovery of BaTiO 3 , high dielectric constants have been reported in compounds with perovskite-type and related structures. These compounds are oxides such as titanates, niobates, and tantalates with d 0 -electron transition-metal ions located within the O octahedra and oxynitrides of SrTaO 2 N and BaTaO 2 N. , Large-capacity ceramic capacitors based on these materials have also attracted interest as energy storage devices that enable the highly efficient use of energy. − …”

To reexamine the crystal structure of the tetragonal oxide previously reported as Ba 5.2 Y 13 Si 8 O 41 , single crystals were prepared by the self-flux method at 1600 °C and X-ray crystal structure analysis was performed. In addition to the fundamental reflections indexed by the cell parameters of the tetragonal system (a = 18.9229(3) Å, c = 5.34880(10) Å), the X-ray diffraction pattern showed faint satellite peaks, suggesting that the oxide is an incommensurate composite crystal. Crystal structure analysis with the fundamental reflection data was performed using an average structure model with split sites of Ba and Y atoms. The space group of the model was I̅ 4̅ 2m, the same as previously reported, and the composition formula determined by refining the occupancies of the split Ba sites was Ba 10.22 Y 26 Si 16 O 81.22 . Ceramics with the composition Ba x Y 26 Si 16 O 71+x (9 ≤ x ≤ 11), which consisted of the tetragonal oxide as the main phase, were synthesized, and their dielectric properties were evaluated. The relative dielectric constants (ε r s) and dielectric losses (tan δs) measured at room temperature for the x = 10.4 ceramics sintered at 1690 °C were 1400 and 0.02 at 10 Hz and 220 and 0.48 at 1 MHz, respectively. The dielectric dispersion could be expressed with the Cole−Cole model. A bulk sample containing the tetragonal oxide with the c axis aligned in one direction was fabricated via unidirectional solidification. The ε r s of the bulk measured in the directions parallel to the c-axis direction (720 at 10 Hz and 350 at 1 MHz) were more than 10 times larger than those in the direction normal to the c-axis direction (49 at 10 Hz and 32 at 1 MHz).

“…Among the metal oxides, nanostructures of BaTiO 3 have been intensively investigated owing to their excellent properties such as large surface to volume ratio, high thermal and chemical stabilities, good biocompatibility, low-cost, lead-free, excellent piezoelectric as well as ferroelectric properties [8][9][10][11]. Due to these, BaTiO 3 nanostructures suitable for many applications such as multilayer ceramic capacitors, nanogenerators, microwave absorbers, thermo optical applications, energy/data storage devices, transducers, resonators, actuators, nonvolatile random-access memory devices, biosensors, hydrophobic coatings, etc [12][13][14][15][16][17][18][19][20][21][22]. However, only a few reports have been reported on glucose sensing and hydrophobic nature of BaTiO 3 nanostructures.…”

BaTiO3 nanostructures have been considered as a potential candidate in recent past for energy and biomedical sector owing to their excellent physiochemical properties such as high dielectric constant, excellent piezoelectric property, good biocompatibility, non-linear optical characteristics etc. Present study reveals on free-standing arrays of BaTiO3 nanostructures were fabricated by hydrothermal conversion of anodic TiO2 nanotubes. Morphological and structural information of the BaTiO3 nanotubes were done using FESEM and XRD studies. FESEM analysis revealed that the fabricated samples were having tubular morphology of average length and pore diameter of 4.63 µm and 290 nm respectively. Cubical perovskite crystalline phase of BaTiO3 was confirmed through XRD analysis. The BaTiO3 nanotube samples had shown a higher sensitivity of 44.43 µA mM-1 cm-2 and a faster response of 0.1 s for glucose detection. The fabricated BaTiO3 nanotubes film also had shown a higher contact angle of 122.700. Therefore, our presently fabrication on Titanium foil study emphasize on arrays of BaTiO3 nanotubes will open up a new window in development of various types of sensing and hydrophobic coating applications.
