The recent developments of energy storage devices are concerned with larger energy storage ability, low loss and good temperature stability. It has a great technological importance in engineering science. The dielectric materials like ceramics and glass ceramics have great interest in electronic ceramic industry due to above concern. The ceramic dielectrics are used as a capacitive element in electronic circuits. The perovskite glass ceramics have very high dielectric constant and low dielectric loss. The high dielectric constant in glass ceramics is attributed to space charge polarization. In order to produce glass ceramics of high dielectric constant, barium titanate glass ceramics is the first discovered ferroelectric perovskite. In this review article, we are summarizing the dielectric behavior of perovskite glass ceramics such as

“…To comprehensively evaluate energy storage performances of lead‐free bulk ceramics for the practical applications of MPPCC, a comparison of W rec and the sintering temperature of lead‐free bulk ceramics for energy storage applications were surveyed in this study, as shown in Figure . One can clearly see from Figure that the sintering temperature of lead‐free bulk ceramics evidently depends on the compositions of the materials.…”

“…In recent years, lead‐free dielectric ceramics for energy storage applications have received increasing attention owing to human health and environmental protection. So far, the study's attention on new lead‐free energy storage ceramics has been paid to BaTiO 3 (BT), (Bi 0.5 Na 0.5 )TiO 3 (BNT), and (K 0.5 Na 0.5 )NbO 3 (KNN)‐based ceramics as a result of their relatively excellent energy storage properties . For example, Wu et al reported BT–Bi(Zn 2/3 Nb 1/3 )O 3 ceramics possessed the W rec of 0.79 J/cm 3 and the energy storage efficiency (η) of 93.5% at 135 kV/cm .…”

Multilayer pulsed power ceramic capacitors require that dielectric ceramics possess not only large recoverable energy storage density (W rec ) but also low sintering temperature (<950°C) for using the inexpensive metals as the electrodes.However, lead-free bulk ceramics usually show low W rec (<2 J/cm 3 ) and high sintering temperature (>1150°C), limiting their applications in multilayer pulsed power ceramic capacitors. In this work, large W rec (~4.02 J/cm 3 at 400 kV/cm) and low sintering temperature (940°C) are simultaneously achieved in 0.9 (K 0.5 Na 0.5 )NbO 3 -0.1Bi(Mg 2/3 Nb 1/3 )O 3 -1.0 mol% CuO ceramics prepared using transition liquid phase sintering. W rec of 4.02 J/cm 3 is 2-3 times as large as the reported value of other (Bi 0.5 Na 0.5 )TiO 3 and BaTiO 3 -based lead-free bulk ceramics. The results reveal that 0.9(K 0.5 Na 0.5 )NbO 3 -0.1Bi(Mg 2/3 Nb 1/3 )O 3 -1.0 mol% CuO ceramics are promising candidates for fabricating multilayer pulsed power ceramic capacitors.

“…The chemical processes of adding glass and using starting materials with ultra-fine particle sizes improve the characteristics of ceramics at low sintering temperatures [3]. Glass additives can have useful effects on the dielectric constant due to their effect in broadening the diffusive phase transition at the Curie temperature, something that is desirable in the application of multilayer ceramic capacitors [4].…”

An overview of ferroelectric glass ceramics, some literature review and some of the important previous studies were focused in this chapter. Nanocrystalline glass–ceramics containing ferroelectric perovskite-structured phases have been included. All modified glasses having ferroelectric ceramics which prepared by different methods are discussed, that producing nanocrystalline glass–ceramics. Then particular tested to their use as dielectric energy storage materials. These materials exhibit promising dielectric properties, indicating good potential for high energy density capacitors as a result of their nanocrystalline microstructures. The results of the analysis are summarised in this chapter to provide an overview of the energy storage characteristics of the different materials produced during the study.
