Effect of a Metallic Implant on the Hysteresis of Ferroelectric BaTiO₃ Ceramics

Abstract

The dielectric constant and hysteresis loops of BaTiO₃ ceramics with and without Pt implants were compared to determine the effect of the implant on the ceramic behavior. Ceramics with 90% relative density and 13.28 µm average grain size were analyzed. The results showed alterations in the ceramic’s coercive field, remanent polarization, and dielectric constant with an implant. The metallic implant affected the internal structure of the BaTiO₃ ceramic, which reduced the ferroelectric properties of the material. In principle, these alterations can be seen as drawbacks, but they open new applications. The results provide insights into the real impact of metallic implants on the ferroelectric properties of the samples.
