摘要

This study examines PbZrO3 ceramics synthesized from nanodispersed PbO and ZrO2 powders with BaTiO3 nanoparticles with sizes of 50, 200, and 400 nm. The incorporation of barium titanate (BaTiO3) nanoparticles into lead zirconate (PbZrO3) ceramics expanded the stability range of the ferroelectric (FE) phase, extending it down to room temperature. As BaTiO3 content increased, the peak of dielectric permittivity shifted toward lower temperatures, while ε′ values rose significantly, reaching a maximum at 10 wt.% BaTiO3 before declining at higher concentrations.
