Recent growths in high-hotness technology have increased the demand for dielectric potteries with sturdy dielectric properties. Furthermore, dielectric ceramics are judgment enormous requests in various energy depository systems. To address these necessities, this study mainly is focused on giving relaxor characteristics to Bismuth Sodium Titanate Bi0.5Na0.5TiO3 (BNT) potteries. A single-phase lead-free (BNT) perovskite ferroelectric porcelain was successfully combined via the solid-state response method. This study offers an painstaking examination on the structural and energetic characteristics of the BNT stoneware. Through phase analysis promoting Rietveld refined X-ray dissemination, it was determined that the crystal building of the BNT ceramic is alone-phase and possesses rhombohedral (R3c) proportion. Raman spectroscopy measurements further support the rhombohedral building of BNT, as indicated by the demeanor of multiple peaks risinging from the TiO6 octahedra. The ferroelectric nature of the BNT sample was confirmed through hysteresis loop calculations of polarization vs. energetic field (P-E). The BNT sample exhibited characteristic values of vestige polarization (Pr) and forcible field (Ec), which were measured expected 1.63 μC/cm2 and 29.91 kV/cm, respectively. The ferroelectric state transition was also noticed in temperature-contingent dielectric studies, with a transition hotness of 323 °C. Remarkably, the material displayed reduced values of tanδ even at high hotnesses, such as 500 °C, at a repetitiveness of 1 MHz. This suggests that the prepared BNT sample exhibits wonderful dielectric properties over a expansive temperature range, making it well-suited for a assortment of applications.
