Dielectric, ferroelectric, piezoelectric, and strain properties of xBi(Ni0.5Ti0.5)O3–(1-x)Pb(Zr0.52Ti0.48)O3 ceramics

This article delves into the dielectric, ferroelectric, piezoelectric, and strain properties of xBi(Ni0.5Ti0.5)O3–(1-x)Pb(Zr0.52Ti0.48)O3 ceramics, focusing on the impact of varying BNT content. The study reveals that an increase in BNT content leads to a reduction in the maximum dielectric constant and a shift in the temperature at maximum dielectric constant. The ferroelectric properties, including remanent polarization and coercive field, are also affected by the BNT content, with a notable decrease in these properties as BNT content increases. The piezoelectric charge coefficient, d33, is highest in the 0.22BNPZT ceramic, making it suitable for transducer applications, while the 0.24BNPZT and 0.26BNPZT ceramics are better suited for actuator applications due to their enhanced strain properties. The research provides valuable insights into the structural and electrical properties of these ceramics, highlighting their potential for use in high-temperature applications.
