“…The dielectric energy storage properties of materials are influenced by the spontaneous polarization of their internal crystal phases and other polarizations occurring within the material. These polarizations can be categorized in terms of the frequency range, including space charge polarization, dipole polarization, ion polarization, and electron polarization, , as shown in Figure c. In the electric frequency range, space charge polarization and dipole polarization are the primary mechanisms at play.…”

Glass-ceramics have great potential as a dielectric material in energy storage. Grain refinement is an effective measure to improve the energy storage performance of dielectric materials. In this study, NaNbO 3 −Ba 0.27 Sr 0.75 Nb 2 O 6 (NN-BSN) complex glass-ceramic was prepared through the investigation and design of heat-treatment processes. The NN perovskite structure and BSN tungsten bronze structure are comparable, and heat treatment was employed to encapsulate the two phases, thereby achieving grain refinement. High-resolution transmission electron microscopy (HR-TEM) images were measured using Gatan Digital software, revealing a maximum lattice spacing of 0.067 nm in the selected area and a maximum interplanar spacing of 0.003 nm −1 in the SAED pattern. Furthermore, the influence of ZrO 2 and TiO 2 , with equal content, on the material structure and performance stability was studied. Raman analysis revealed that ZrO 2 exists as an intermediate network in the structure, resulting in good high-temperature stability of the samples. TiO 2 acted as a crystal nucleating agent, promoting grain growth and enhancing the polarization performance of the samples.

“…Liu et al [5] reported that the addition of CeO 2 decreased the activation energy of crystallization and enhanced the dielectric constant as well as breakdown strength in SrO-BaO-Nb 2 O 5 -B 2 O 3 -SiO 2 system glasses. Our previous research [6] found that the addition of Gd 2 O 3 to the glass-ceramics improved the dielectric property and energy-storage density in SrO-BaO-Nb 2 O 5 -B 2 O 3 system glass-ceramics. Recently, Chen et al [7] selected AlF 3 and MnO 2 as dopants to optimize the microstructure and dielectric properties of the strontium barium titanate glass-ceramics.…”

SrO–BaO–Nb2O5–B2O3system glass-ceramics with Gd2O3/BaF2addition have been prepared by controlled crystallization method. The effect of Gd2O3/BaF2addition on the phase evolution, dielectric properties and energy storage properties has been investigated. The addition of Gd2O3/BaF2to the glass-ceramics changes the dielectric property and energy storage density. The glass-ceramics with 0.5 mol% Gd2O3and 4.5mol% BaF2heat treated at 850°C/3h possesses a dielectric constant of 125, a breakdown strength of 1055 kV/mm and energy storage density of 6.16J/cm3, which are promising materials for high energy storage density dielectrics.

Synthesis of Eu³⁺‐doped BaBi₂Ta₂O₉ based glass‐ceramic nanocomposites: Optical and dielectric properties

In this paper we report for the first time synthesis of Eu3+‐doped transparent glass‐ceramics (TGC) with BaBi2Ta2O9 (BBT) as the major crystal phase using the glass system SiO2–K2O–BaO–Bi2O3–Ta2O5 by melt quenching technique followed by controlled crystallization through ceramming heat treatment. DSC studies were conducted in order to determine a novel heat‐treatment protocol to attain transparent GCs by controlling crystal growth. The structural properties of the BBT GCs have been investigated using XRD, FE‐SEM, TEM and FTIR reflectance spectroscopy. Optical band gap energies of the glass‐ceramic samples were found to decrease with respect to the precursor glass. An increased intensity of emission along with increase in the average lifetime of Eu3+ was observed due to incorporation of Eu3+ ions into the low‐phonon energy BBT crystal site. The local field asymmetric ratios of all the samples were observed greater than unity. The dielectric constant (εr), dielectric loss, and dissipation factor values of both the base glass and ceramized samples were found to decrease with increase in frequency.
