Dielectric inspection of BaZr0.2Ti0.8O3 ceramics under bias electric field: A survey of polar nano-regions

Energy Conversion Capacity of Barium Zirconate Titanate

“…Calcination at a temperature above 1100 • C should not be undertaken, because of the agglomeration and enlargement of Ba(Zr x Ti 1−x )O 3 particles. The compression of large calcined particles might result in a low bulk density of the sintered ceramics [20,21]. Table 1 presents the measurable bulk density of sintered Ba(Zr x Ti 1−x )O 3 .…”

Dielectric and ferroelectric properties of the sol‐gel–derived Zr‐doped Ba0.7Sr0.3TiO3 polycrystalline ceramic systems

“…Furthermore, in most cases the ceramics were processed by the conventional solid‐state sintering route . Limited attempts have been made to report the dielectric properties of the Ba 0.7 Sr 0.3 Zr x Ti 1−x O 3 (BSZT) ceramics despite of the fact that extensive consideration has been given to Zr‐doped BaTiO 3 or SrTiO 3 polycrystalline ceramic systems . This study reports, synthesis of the BSZT ceramics using stoichiometries formula Ba 0.7 Sr 0.3 Ti 1−x Zr x O 3 .…”

“…Among these Zr-doped BaTiO 3 solid solution (BaZrTiO 3 or BZT) has been reported to bring out interesting alteration in T c and dielectric response at varying Zr content. [4][5][6][7] An isovalent substitution of Zr 4+ for Ti 4+ on the B-site in BaTiO 3 -based ceramics results in a pinching effect on the T c. 8 Recently, Wang et al 9 proposed that replacing Ti 4+ by Zr 4+ doping in the BST crystal structure can enhance its dielectric response. They synthesized Ba 0.6 Sr 0.4 (Zr 0.2 Ti 0.8 )O 3 ceramics using spark plasma sintering (SPS) at 1270°C for 5 min.…”

“…11 Limited attempts have been made to report the dielectric properties of the Ba 0.7 Sr 0.3 Zr x Ti 1Àx O 3 (BSZT) ceramics despite of the fact that extensive consideration has been given to Zr-doped BaTiO 3 or SrTiO 3 polycrystalline ceramic systems. 8,12,13 This study reports, synthesis of the BSZT ceramics using stoichiometries formula Ba 0.7 Sr 0.3 Ti 1Àx Zr x O 3 . The dielectric properties were measured in a broad temperature regime using a frequency range from 1 kHz to 1 MHz.…”

Effects of sintering temperature on the microstructure and dielectric properties of BaZr0.2Ti0.8O3 ceramics

“…Hence, these materials are found applications in ceramic capacitors, piezoelectric actuators, thermistors and tunable microwave devices [5][6][7][8][9][10][11].…”
