Abstract

This study has been conducted to determine the optimum value for poling treatment parameters of BaTiO 3 as piezo-ceramic material using a home-built DC poling system. The three main poling parameters that has been studied were electric field (Ep), temperature (Tp) and time (tp) treatments. Single phase BaTiO 3 piezo-ceramic stabilized in tetragonal structure was successfully prepared using conventional solid-state sintering. The selection range of Ep and Tp for poling treatment were based on prior ferroelectric hysteresis measurement and determination of Curie temperature, Tc tests, respectively. The results showed that BaTiO 3 has low coercive field, Ec (∼2.42 kV/cm), remanent polarization, Pr ∼4.90 μC/cm2 and large maximum polarization, Pm (∼17.59 μC/cm2) values with Tc of 139°C. Based on the studied parameter ranges, the highest piezoelectric constant, d33 value ∼190 pC/N was obtained with poling electric field magnitude of 1.5Ec at 60°C for 10 min. Structure and morphology BaTiO 3 after poling treatment were also investigated. Developed poling system effectively reorient the domain alignments and the optimum treatment parameters were comparable with other BaTiO 3 studies.
