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

“…The soft ceramics hold good for sensing and actuating applications [27], while the hard ones are principally used in high voltage, mechanical loads, and power applications [36]. The effect of modi ed composition and donor/acceptor rare-earth ions on the MPB of BZT-BCT has been explored to yield the optimal PE properties [37][38][39][40][41][42][43][44]. Nevertheless, a very few investigations were available on Nb-doped BZT-BCT [41,43,44] (i.e., BZT-BCNT) out of which, in particular, Dy 3+ dopant system is not available to the best of our knowledge.…”

Perovskite structured Dy doped BZT-BCNT system has been investigated with variation of Dy doping through the solid-state reaction method. X-ray diffraction (XRD) and microscopic studies confirm the results in the rhombohedral stoichiometry without any secondary phases, and uniform grain growth, respectively. Tolerance factor and electronegativity also confirm the presence of Dy doping in BZT-BCNT ceramic system with a stable rhombohedral crystallinity forming vacancy sites for oxygen ions. Optimum piezoelectric properties in non-Pb piezoelectric ceramic systems were obtained due to trivalent donor Dy doping at A-site and pentavalent donor Nb at B-site are possible members for actuator and energy harvesters. Dielectric and piezoelectric studies signifying the rhombohedral perovskite behavior of this lead-free ceramic system confess that the proposed investigation could yield further potential piezoelectric sensors and actuators applicative futuristic studies.

“…Compounds with double perovskite structure are versatile, capable of generating a large family of solids. These compounds are investigated due to their physical properties as semiconducting, ferroelectric, dielectric, pyroelectric, piezoelectric and multiferroic [2,3]. Further, A 2 BB'O 6 double perovskite type shows magnetic and magnetoresistance properties, while the AA'BB'O 6 type have been investigated for their catalytic properties [4].…”

In this work were synthesized new catalysts of stoichiometries Sr0.8K0.2TiCu0.10O3, Sr0.7K0.3TiCu0.15O3 and Sr0.5K0.5TiCu0.25O3 by spray pyrolysis method. The synthesis conditions were optimized to obtain single phase powder of titanates of double perovskite structure, with an ultrasound vibration frequency of 1.3 MHz at 700 °C under air flow. The average crystallite size of the powders, determined by the Scherrer equation and using the Jade Plus 8 software, was at around 9 nm. The powder morphology was analyzed by scanning electron microscopy (SEM). The Sr0.5K0.5TiCu0.25O3 system showed particles with smooth surfaces, spherical and with smaller agglomerates than Sr0.8K0.2TiCu0.10O3, Sr0.7K0.3TiCu0.15O3 systems. This phenomenon suggests that the stoichiometry changes the aspect of the particle surface, which may influence in the catalytic activity. Thus, particles without roughening and smaller size can act as promising catalysts.
