| Abstract Scope |
This study focused on the synthesis of (1-x)BaTiO3-(x)BiYO3 materials, with varying x values (2, 4, 6, 8, and 10 mol%), to enhance the energy storage efficiency. Characterization of the synthesized ceramics was performed using X-ray Diffractometry (XRD), X-ray Absorption Spectroscopy (XAS), density measurements, and assessments of dielectric and ferroelectric properties. The XRD results revealed the presence of a single perovskite structure in all conditions, while the XAS data indicated local substitution of Bi and Y in B and Ti sites. Notably, the dielectric constant of the samples displayed its maximum value at x = 2 mol%, while the transition temperature decreased with higher BiYO3 content. Furthermore, the polarization-electric field (P-E) hysteresis loops of the ceramic systems exhibited significant variations with BiYO3 content. In addition to these findings, energy storage efficiency was calculated from the ferroelectric hysteresis loop which shows maximum value of energy storage efficiency at x = 10 mol%. |
