“…However, there is a slight shift of the reflections to lower 2θ values after the incorporation of W/Cr. According to the XRPD data, the Rietveld Refinement technique was used to calculate the parameters of the the pure Bi 4 Ti 3 O 12 structure (Figure 3a) as follows, a = 5.4457 Å; b = 5.4087 Å; c = 32.8378 Å; V = 967 Å 3 and a / b = 1.0068 (Refinement index: R p = 5.67; R wp = 7.42; R B = 4.74; and λ 2 = 1.37), which are basically in agreement with the values determined by Ivanov et al [22]. Here, the factor with the form of a / b was used to indicate the degree of the lattice distortion of orthorhombic structure (ab.…”

Taking Bismuth Titanate (Bi4Ti3O12) as a Aurivillius-type compound with m = 3 for example, the ion (W6+/Cr3+) doping effect on the lattice distortion and interlayer mismatch of Bi4Ti3O12 structure were investigated by stress analysis, based on an elastic model. Since oxygen-octahedron rotates in the ab-plane, and inclines away from the c-axis, a lattice model for describing the status change of oxygen-octahedron was built according to the substituting mechanism of W6+/Cr3+ for Ti4+, which was used to investigate the variation of orthorhombic distortion degree (a/b) of Bi4Ti3O12 with the doping content. The analysis shows that the incorporation of W6+/Cr3+ into Bi4Ti3O12 tends to relieve the distortion of pseudo-perovskite layer, which also helps it to become more stiff. Since the bismuth-oxide layer expands while the pseudo-perovskite layer tightens, an analytic model for the plane stress distribution in the crystal lattice of Bi4Ti3O12 was developed from the constitutive relationship of alternating layer structure. The calculations reveal that the structural mismatch of Bi4Ti3O12 is constrained in the ab-plane of a unit cell, since both the interlayer mismatch degree and the total strain energy vary with the doping content in a similar trend to the lattice parameters of ab-plane.

“…Generally speaking, the electric field strength is a vector. In practical applications, in many cases, the standard, that is, the vacuum dielectric constant ε is selected as 0 [12]. As the specific permittivity of the dimensionless constant, the permittivity ε of the dielectric body is less than zero in the vacuum permittivity ε, as shown in the following formula:…”

Nano has its small size and specific characteristics that are different from other materials, bringing a climax to the world’s on-site nano research and material development. In the ceramic industry, the nanometer is an important research object in the ceramic industry. This article aims to study nanomaterials and their application in Tang Sancai. The experiment in this paper shows from the Table that the sales volume of nanotechnology used in 2016-1020 is getting higher and higher, from 35.35 million yuan in 2016 to 10.43 million yuan in 2020, while the sales volume of ceramics that do not use nanotechnology has increased from 3567 in 2016. Ten thousand yuan has become 26.32 million yuan in 2020. It can be seen that ceramics using nanotechnology are more popular.

Bi4−x Nd x FeTi2O12 (BNFTO, x = 0, 0.5, 1.0, and 1.5) Aurivillius three‐layered ceramics are prepared via a solid‐state reaction method. The crystal structure of the compounds reveals that the compounds exhibit a major orthorhombic structure with the B2cb space group. Slight distortions in the orthorhombic unit cell and an increase in cell volume with the doping of Nd are observed. Highly dense randomly oriented plate‐like nonuniform grains are observed in the micrographs of the ceramics. A decrease in energy bandgap values is noticed in Nd‐doped ceramics from 2.88 to 2.18 eV. An increase in polarization values is observed with Nd doping due to the improved grain boundaries. The appearance of a weak ferromagnetic nature at low temperature followed by a decline in magnetic interaction at room temperature (RT) is observed for all compounds. The frequency and temperature variations of the dielectric constant are investigated. The frequency and temperature variations of the impedance measurements indicate that compounds exhibit non‐Debye‐type electrical relaxations and a negative temperature coefficient of resistance. Furthermore, single‐peak relaxations are predominant for all measured samples, mainly the contribution of intragranular grain regions. This makes Nd‐dopant BNFTO Aurivillius ceramics have a great research value for RT multiferroic applications.
