“…Many ferroelectric glass-ceramics use niobium oxide as a key constituent in the SiO 2 and/ or B 2 O 3 precursor glass, because it has clearly shown its primordial role in obtaining good ferroelectricity in niobite materials. Different types of ferroelectric glass-ceramic systems such as (BaO, Na 2 O)-Nb 2 O 5 , (8) (SrO, BaO)-Nb 2 O 5 , (9) (Na 2 O, SrO)-Nb 2 O 5 , (10) (K 2 O, SrO, BaO)-Nb 2 O 5 (11) have been investigated widely. For instance, Takashi et al (12) reported that (BaO, Na 2 O)-Nb 2 O 5 -P 2 O 5 glass-ceramics crystallised in phosphoniobate system.…”

A series of (1−x)[(2BaO–0·5Na2O)–1P2O5] –xNb2O5 (BNPN, x=0·41, 0·43, 0·45, 0·48) glass-ceramics based on phosphate glasses have been prepared via a controlled-crystallisation route. The structure, dielectric properties, interfacial polarisation and energy storage properties were systematically investigated. The x-ray diffraction results showed the simultaneous presence of Ba2NaNb5O15 tungsten bronze structure (TTB) and the NaNbO3 perovskite. A stable dielectric constant over a temperature range from 25–200°C, low dielectric losses less than 0·03 and excellent frequency stability at room temperature were obtained. The decrease of niobium content promoted the TTB crystallisation with improvement of the high dielectric properties of the system. The optimum of the dielectric constant and recoverable energy storage density were obtained for BNP41 crystallised at 1000°C. Analyses of the complex impedance indicated that the niobium content and crystallisation temperature affect the interfacial polarisation.

“…Compared to ferroelectric ceramics, glass–ceramic dielectrics are well‐known for very low or zero porosity, possessing higher dielectric constant and breakdown strength . Glass‐ceramic dielectrics in which a ferroelectric phase is devitrified via the crystallization of a precursor glass, is widely researched as the most promising candidate in the fields of high‐voltage and energy storage systems …”

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.
