Abstract

This study focuses on the compound (Na₀.₅Bi₀.₅)ₓMg₁₋ₓ[(Ti₀.₈Zr₀.₂)₀.₉(Nb₂⁄₃Zn₁/₃)₀.₁]O₃ (BNTZZN-x%Mg), which was synthesized using the molten salt method for x = 0.00, 0.02, 0.06, and 0.08. The resulting samples were calcined at 900 °C for 4 hours and subsequently sintered at 1150 °C. The measured densities were found to be close to the theoretical values. X-ray diffraction (XRD) analysis confirmed the formation of a pure perovskite phase. Scanning electron microscopy (SEM) images revealed a slight variation in grain size with increasing Mg content. Overall, the material exhibited relatively high purity and density. Dielectric properties were measured on the single-phase ceramic, and their evolution was studied over a temperature range of 27 °C to 227 °C across various frequencies.
