PZT-based materials with bilayered structure: preparation and ferroelectric properties

In the present work, bilayered PZT-based ceramic materials were successfully produced via dry pressing and sintering. The densification, compositional phase, and microstructure of the materials prepared were investigated. Ferroelectric properties of the materials were measured and the relationship between property and layer volume composition was discussed. The present work reported a simply method to fabricate ferroelectric materials incorporating good parameters, such as higher remanent polarization, dielectric constant, and lower dielectric loss, which meet the material demand of both higher performance and longer service time.
