Study of Structural, Dielectric, Electrical and Ferroelectric properties of (Bi 0.9 Dy 0.1 )(Ni 0.5 Ti 0.5 )O 3 Ceramic

The synthesis and analysis of dysprosium -modified bismuth nickel titanate (BNTO) ceramic, with 10% dysprosium content, by using the solid-state reaction method. The ceramic was calcined at 850 ° C to prepare it for further examination. The primary objective of this study was to inquire the synthesis, structural, dielectric, electrical, and ferroelectric properties of the ceramic compound (Bi 0.9 Dy 0.1 )(Ni 0.5 Ti 0.5 )O 3 . Numerous inquisitive techniques, including X-ray diffraction (XRD) and phase-sensitive measurements, were employed to investigate these characteristics. Scanning electron microscopy (SEM) was employed to investigate the surface morphology of the synthesized ceramic, revealing a uniform structural arrangement and overall homogeneity. To verify the material's composition and purity, energy-dispersive X-ray (EDX) analysis was conducted, yielding atomic percentage values consistent with the expected elemental makeup. The temperature-dependent ac conductivity provides insights into the material's conductive behavior. The dielectric properties were analyzed across a selected range of frequencies and temperatures, giving a deeper understanding of its electrical characteristics. Additionally, impedance spectroscopy was used to assess the dielectric outcome and further interpret the material's electrical behavior. Additionally, room-temperature PE hysteresis loops demonstrated weak ferroelectric behavior, characterized by a remnant polarization (Pr) of 1.09 μC/cm 2 . The study concludes that the improved dielectric and electrical performance of this ceramic suggests its applicability in various advanced electronic devices.
