Energy Conversion Capacity of Barium Zirconate Titanate

Abstract: In this study, we investigated the effect of zirconium content on lead-free barium zirconate titanate (BZT) (Ba(ZrxTi1−x)O3, with x = 0.00, 0.01, 0.03, 0.05, and 0.08), which was prepared by the sol–gel method. A single-phase perovskite BZT was obtained under calcination and sintering conditions at 1100 °C and 1300 °C. Ferroelectric measurements revealed that the Curie temperature of BaTiO3 was 399 K, and the transition temperature decreased with increasing zirconium content. At the Curie temperature, Ba(Zr0.0… Show more

“…22,30 The decrease in ϵ r value after Curie transition temperature in ferroelectric ceramics attributes to the disorientation of the thermally agitated dipoles from the applied electric field. 15,31 The microwave sintered BZT exhibits a similar trend for tan δ versus temperature and a relaxation peak is noticed at T c . Both BZT and PZT ceramics exhibits dielectric relaxation which is attributed to the thermally activated ferroelectric dipoles.…”

“…A maximum ϵ r value of 12,200 is observed at 31 °C at 1 MHz owing to sharp ferro to para phase transition at this temperature, beyond which the dielectric constant decreases (as shown in Figure ). Similar results are observed in previous reports. , The decrease in ϵ r value after Curie transition temperature in ferroelectric ceramics attributes to the disorientation of the thermally agitated dipoles from the applied electric field. , The microwave sintered BZT exhibits a similar trend for tan δ versus temperature and a relaxation peak is noticed at T c .

“…The lead-free dielectric material for energy storage application has progress greatly in recent years, especially for the Ba(Zr x Ti 1−x )O 3 (BZT)-based systems [ 1 , 2 , 3 , 4 , 5 ]. The large bandgap, high dielectric constant, and low dielectric loss make them an excellent material for energy storage applications, and they have great advantages in high-power and high-energy-capacitor energy storage applications.…”

“…The ferroelectric properties of barium titanate have been also taken into account during the designing of the materials fabricated for the energy storage application [12][13][14] or the energy conversion [15]. On the other hand, barium titanate has also found wide application in medicine, e.g., in tissue engineering [16][17][18][19][20][21].…”
