Preparation of (Ba_1−xSr_x)(Zr_xTi_1−x)O₃Ceramics via the Solid State Reaction Method

Influence of seed nano-crystals on electrical properties and phase transition behaviors of Ba0.85Sr0.15Ti0.90Zr0.10O3 ceramics prepared by seed-induced method

“…[3,4] The ceramic process has many techniques such as solgel, [10,11] molten salt method, [12,13] and the conventional mixed oxide method. [14,15] The different methods have effects on the structure as well as ferroelectric properties or electrical properties. Mahesh et al [4] was reported that the enhanced dielectric properties of Ba(Zr 0.…”

“…Mahesh et al [4] was reported that the enhanced dielectric properties of Ba(Zr 0. 15 Ti 0.85 )O 3 by using coldisostatic pressing, the consisted of a high dielectric constant of ~14,000 at 1 kHz. In this work, we would like to introduce the seed-induced method for modifying the crystal phase to enhance the dielectric properties.…”

Effects of Ca2+substitution on dielectric properties of (Ba0.7Sr0.3)(Ti0.9Zr0.1)O3ceramics

“…6,7) To obtain a high dielectric constant at room temperature, many researchers have investigated the effect of ion substitution on various types of BaTiO 3 -based ceramics. [8][9][10][11][12][13][14] Specifically, it has been reported that the substitution of Sr 2+ , Ca 2+ , and/or La 3+ ions for Ba 2+ ions in Ba(Ti 0.9 Zr 0.1 )O 3 ceramics resulted in a high dielectric constant, above 10,000 at room temperature. [12][13][14] However, most of these studies discussed the effect of A-site substitution on the microstructure of these ceramics and the relationships between the microstructure and the dielectric properties of ABO 3 perovskite dielectrics.…”

[12][13][14] However, most of these studies discussed the effect of A-site substitution on the microstructure of these ceramics and the relationships between the microstructure and the dielectric properties of ABO 3 perovskite dielectrics. Moreover, the improved dielectric properties of these ceramics have only been explained by the shift in the phase transition temperature to room temperature.…”

Low Temperature Synthesis of Complex Ba1–xSrxTi1–yZryO3 Perovskite Nanocrystals

“…Although several synthetic strategies for the preparation of perovskite nanocrystals of formula Ba 1– x Sr x TiO 3 , and BaTi 1– y Zr y O 3 , have been developed, very few reports exist describing the synthesis of Ba 1– x Sr x Ti 1– y Zr y O 3 nanocrystals. In such cases, four-cation perovskite phases are typically synthesized via solid state reaction, , sol–gel, , and combustion synthesis . These approaches require thermal treatment at temperatures above 700 °C to produce a crystalline and phase pure product; this results in micrometer-sized grains with a broad size distribution.…”
